Use 3.14 as pi. Use the formula V= pi x radius squared x height.
A cylinder has a volume of 239 cubic centimetres and a height of 6 centimeters. what is the Radius.
First, we rearrange the formula V= pi x radius squared x height to solve for the radius:
radius squared = V / (pi x height)
radius = square root of (V / (pi x height))
Substituting the given values, we get:
radius = square root of (239 / (3.14 x 6))
Simplifying this expression gives:
radius = square root of 12.0649
radius ≈ 3.47 cm (rounded to two decimal places)
To find the radius of the cylinder, we can rearrange the formula for volume:
V = π x r^2 x h
Given that the volume (V) is 239 cubic centimeters and the height (h) is 6 centimeters, we can substitute these values into the equation and solve for the radius (r).
239 = 3.14 x r^2 x 6
Dividing both sides of the equation by (3.14 x 6):
239 / (3.14 x 6) = r^2
r^2 = 12.06
To find the radius, we can take the square root of both sides of the equation:
r ≈ √(12.06)
Calculating the square root of 12.06 gives us approximately 3.47.
Therefore, the radius of the cylinder is approximately 3.47 centimeters.
