Answer:
Step-by-step explanation:
The formula for volume of a cylinder is..
V = πr²h where r is the radius and h is the height. We are given V = 452 and h = 9, plug those values in and solve for r
452 = πr²(9)
452/(9π) = r² (divide both sides by 9π)
√[452/(9π)] = r (take the square root of both sides)
(√452)/(√9π) = r (the next steps simplify the equation)
(2√113)/(3√π) = r
[(2√113)√π)]/[3(√π)(√π)] = r
[2√(113π)]/(3π) = r
