The circumference of a circle equals pi times the diameter. Using 3.14 to approximate pi, what is the approximate circumference in inches of a circle with a diameter of fraction start1 fraction end 2 in.?
The formula to calculate the circumference of a circle is C = πd, where C represents the circumference and d represents the diameter.
Given that the diameter of the circle is 1/2 inch, we can calculate the circumference using the approximation of π as 3.14.
C = 3.14 * (1/2)
C = 3.14/2
C ≈ 1.57 inches
Therefore, the approximate circumference of the circle with a diameter of 1/2 inch is 1.57 inches.
9/4 is close to the square root of what integer?
We need to find an integer whose square root is close to 9/4.
To solve this, we will find the square root of some integers and see which one is close to 9/4.
√1 = 1
√2 ≈ 1.414
√3 ≈ 1.732
√4 = 2
√5 ≈ 2.236
√6 ≈ 2.449
√7 ≈ 2.646
√8 ≈ 2.828
√9 = 3
From the values above, we can see that the square root of 9 is 3, which is the closest integer to 9/4.
Therefore, 9/4 is close to the square root of 9.
Bot that’s incorrect
Apologies for the incorrect response.
To find an integer whose square root is close to 9/4, we can square different integers until we find one that is close to 9/4.
Let's try squaring some integers and comparing them to 9/4:
1^2 = 1
2^2 = 4
3^2 = 9
4^2 = 16
From the values above, we can see that 3^2 = 9, which is the closest integer to 9/4. Therefore, 9/4 is close to the square root of 9.
To find the approximate circumference of a circle with a diameter of fraction start1 fraction end 2 inches, we can use the formula:
Circumference = pi * diameter.
Given that we are approximating pi as 3.14 and the diameter is fraction start1 fraction end 2 inches, we can plug those values into the formula:
Circumference = 3.14 * fraction start1 fraction end 2.
Now, we can perform the calculation:
Circumference = 3.14 * fraction start1 fraction end 2
≈ 3.14 * 1.5
≈ 4.71 inches.
Therefore, the approximate circumference of the circle is 4.71 inches.
To find the approximate circumference of a circle, you can use the formula: circumference = pi * diameter.
In this case, you have a diameter of fraction start1 fraction end 2 inches. Let's substitute this value into the formula using the approximation of pi as 3.14:
circumference ≈ 3.14 * fraction start1 fraction end 2
To perform the calculation, multiply 3.14 by fraction start1 fraction end 2:
circumference ≈ 3.14 * fraction start1 fraction end 2 ≈ 3.14 * 1.5
Now, let's calculate the approximate circumference:
circumference ≈ 3.14 * 1.5 ≈ 4.71 inches
Therefore, the approximate circumference of a circle with a diameter of fraction start1 fraction end 2 inches is approximately 4.71 inches.
