Calculate the volume of a cylindrical steel bar which is 8cm long 3•5cm in diameter
To calculate the volume of a cylindrical steel bar, you can use the formula:
Volume = π * r^2 * h
where π is a mathematical constant approximately equal to 3.14159, r is the radius of the cylinder, and h is the height or length of the cylinder.
Given that the diameter of the steel bar is 3.5 cm, the radius (r) can be calculated by dividing the diameter by 2:
r = 3.5 cm / 2 = 1.75 cm
The length of the steel bar (h) is 8 cm.
Now, we can substitute the values into the formula and calculate the volume:
Volume = π * (1.75 cm)^2 * 8 cm
Volume = 3.14159 * 3.0625 cm^2 * 8 cm
Volume = 76.740 cm^3
Therefore, the volume of the cylindrical steel bar is approximately 76.740 cm^3.
Please simplify it don't use words just letters
Sure! Here is the simplified calculation:
Volume = π * (r^2) * h
Given:
r = 1.75 cm (radius)
h = 8 cm (height)
Substituting the values:
Volume = π * (1.75^2) * 8
Now calculate:
Volume = 3.14159 * (1.75^2) * 8
Volume ≈ 76.740 cm^3
Give me the same answer but this time let π be 22/7.
Pleaseeeeee
Sure! Here is the simplified calculation considering π as 22/7:
Volume = (22/7) * (r^2) * h
Given:
r = 1.75 cm (radius)
h = 8 cm (height)
Substituting the values:
Volume = (22/7) * (1.75^2) * 8
Now calculate:
Volume = (22/7) * (3.0625) * 8
Volume ≈ 175.4286 cm^3
Therefore, the volume of the cylindrical steel bar is approximately 175.4286 cm^3.
2×22×6×23/7
To simplify the expression 2×22×6×23/7, we can perform the multiplication first and then divide.
First, multiplying the numbers:
2 × 22 × 6 × 23 = 6,072
Now, dividing by 7:
6,072 ÷ 7 = 867.4286
Therefore, 2×22×6×23/7 simplifies to approximately 867.4286.
22×1•5^2×8=
To simplify the expression 22×1•5^2×8, we can perform the operations in order of multiplication and exponentiation.
First, let's square 1.5:
1.5^2 = 2.25
Next, multiply 22 by 2.25:
22 × 2.25 = 49.5
Finally, multiply 49.5 by 8:
49.5 × 8 = 396
Therefore, 22×1•5^2×8 simplifies to 396.
396÷7
To simplify the expression 396÷7, we can perform the division calculation.
396 ÷ 7 = 56
Therefore, 396÷7 simplifies to 56.
(B) calculate the TSA of the cylinder
To calculate the Total Surface Area (TSA) of a cylinder, you need to sum the areas of its two circular bases and the lateral surface area.
The formula for calculating the TSA of a cylinder is:
TSA = 2πr(r + h)
Given that the radius (r) of the cylinder is 1.75 cm and the height (h) is 8 cm, substitute these values into the formula:
TSA = 2 × (22/7) × 1.75(1.75 + 8)
Simplify the expression:
TSA = 2 × (22/7) × 1.75 × 9.75
TSA ≈ 108.857 cm²
Therefore, the Total Surface Area (TSA) of the cylinder is approximately 108.857 cm².
I mean the TSA of a cylinder that is 8cm long and 3•5cm in diameter
To calculate the Total Surface Area (TSA) of a cylinder, you need to sum the areas of its two circular bases and the lateral surface area.
Given that the cylinder is 8 cm long and has a diameter of 3.5 cm, we first need to find the radius (r) of the cylinder. The radius is half the diameter.
r = 3.5 cm / 2 = 1.75 cm
Now, we can calculate the TSA using the formula:
TSA = 2πr(r + h)
Where:
- π is a mathematical constant approximately equal to 3.14159
- r is the radius of the cylinder
- h is the height or length of the cylinder
Substituting the given values:
TSA = 2π(1.75 cm)(1.75 cm + 8 cm)
Now, simplify and calculate:
TSA = 2π(1.75 cm)(9.75 cm)
Using the approximate value of π as 3.14159:
TSA ≈ 2 * 3.14159 * 1.75 cm * 9.75 cm
TSA ≈ 107.840 cm²
Therefore, the Total Surface Area (TSA) of the cylinder with a length of 8 cm and a diameter of 3.5 cm is approximately 107.840 cm².

Therefore, the Total Surface Area (TSA) of the cylinder with a length of 8 cm and a diameter of 3.5 cm is approximately 107.840 cm².
What does this * stand for
The * symbol represents multiplication. In mathematical notation, the * is commonly used as a symbol to indicate multiplication instead of using the "x" symbol. So when you see * between numbers, it means that those numbers are being multiplied together.
How many litres of water will a cylindrical pipe hold if it's 1m long and 7 cm in diameter
To calculate the volume of a cylindrical pipe, we can use the formula:
Volume = π * r^2 * h
Where π is a mathematical constant approximately equal to 3.14159, r is the radius of the pipe, and h is the height or length of the pipe.
Given that the pipe is 1 m long and has a diameter of 7 cm, we first need to find the radius (r) of the pipe. The radius is half the diameter.
r = 7 cm / 2 = 3.5 cm
Since volume is usually measured in liters, we can convert the volume from cubic centimeters to liters by dividing by 1000.
Now, we can calculate the volume:
Volume = (π * r^2 * h) / 1000
Volume ≈ (3.14159 * (3.5 cm)^2 * 100 cm) / 1000
Volume ≈ 38.48465 cm³
Converting cm³ to liters:
Volume ≈ 38.48465 cm³ / 1000 = 0.03848465 liters
Therefore, the cylindrical pipe will hold approximately 0.038 liters (or 38.48465 milliliters) of water.
Please simplify it, no bracket
Certainly! Here is the simplified calculation for the volume of the cylindrical pipe without brackets:

Volume ≈ 3.14 * (3.5 cm)^2 * 100 cm / 1000
Now, calculate:
Volume ≈ 3.14 * 3.5^2 * 100 / 1000
Volume ≈ 38.48 cm³
Converting cm³ to liters:
Volume ≈ 38.48 cm³ / 1000 = 0.038 liters
Therefore, the cylindrical pipe will hold approximately 0.038 liters (or 38.48 milliliters) of water.
