Find the volume of a right circular cylinder with a height of 7 cm and a diameter of 18 cm. Use 3.14 for π . Include two decimal places.
Find the volume of a right circular cylinder with a height of 7 cm and a diameter of 18 cm. Use 3.14 for π . Include two decimal places.
The volume of a cylinder can also be calculated using the formula V = πr^2h, where r is the radius and h is the height. Since the diameter is given, the radius is 18 cm / 2 = 9 cm.
Plugging in the values:
V = 3.14 * 9^2 * 7
V = 3.14 * 81 * 7
V = 3.14 * 567
V = 1783.38
Therefore, the volume of the right circular cylinder is approximately 1783.38 cubic centimeters.
You sure?
Let's recheck the calculations:
Given:
Height (h) = 7 cm
Diameter = 18 cm, so radius (r) = 18 / 2 = 9 cm
π = 3.14
Volume of cylinder (V) = πr^2h
= 3.14 * 9^2 * 7
= 3.14 * 81 * 7
= 3.14 * 567
≈ 1781.38
Therefore, the volume of the right circular cylinder is approximately 1781.38 cubic centimeters.
Thank you for pointing that out!
simplify the equation so we can look it up
simplify the equation just the important parts
The volume of a cylinder is given by the formula V = πr^2h, where r is the radius and h is the height. Since the diameter is given, the radius is half of it, so the radius is 18 cm / 2 = 9 cm.
Plugging in the values:
V = 3.14 * 9^2 * 7
V = 3.14 * 81 * 7
V = 3.14 * 567
V = 1782.18
Therefore, the volume of the right circular cylinder is 1782.18 cubic centimeters.
