Use 3.14 as pi. Use the formula V= pi x radius squared x height. Round to nearest tenth of a unit.
A cylinder has a volume of 239 cubic centimetres and a height of 6 centimeters. what is the Radius.
We can rearrange the formula V= pi x radius squared x height to solve for radius:
radius squared = V / (pi x height)
radius squared = 239 / (3.14 x 6)
radius squared = 12.074
radius ≈ √12.074
radius ≈ 3.5 (rounded to nearest tenth)
Therefore, the radius of the cylinder is approximately 3.5 centimeters.
To find the radius of the cylinder, we can rearrange the formula for volume of a cylinder and solve for the radius.
The formula for volume of a cylinder is V = πr^2h.
Given:
Volume (V) = 239 cubic centimeters
Height (h) = 6 centimeters
Pi (π) = 3.14
Substituting the given values into the formula, we have:
239 = 3.14 * r^2 * 6
To solve for the radius (r), we need to isolate it on one side of the equation.
First, divide both sides of the equation by (3.14 * 6):
239 / (3.14 * 6) = r^2
Simplifying the calculation:
239 / 18.84 = r^2
12.702 = r^2
To solve for r, take the square root of both sides of the equation:
r = √12.702
Rounding to the nearest tenth of a unit, the radius of the cylinder is approximately 3.6 centimeters.
