Question

A cylinder has a height of 21 cm and a volume of 11,144 cm³. What is the radius of the cylinder? round your answer to the nearest whole number.

Answer 1

Answer:

13 cm

Explanation:

h = 21 cm, V = 11,144 cm^3

V = π r^2 h

so

$r=\sqrt{\frac{V}{\pi h}}=\sqrt{\frac{11,144}{\pi\times21}}=13 cm$
