Question

A cylinder has a radius of 5 m and a height of 11 m. Identify the volume of the cylinder to the nearest tenth.

Answer 1

86,405 cm³

Explanation:

V = cross-sectional area × height = πr²h = 3.142 × 5² × 1100cm

= 86,405 cm³

Answer 2

863.9 m³

Explanation:

Cylinder volume is V = πr²h. Here the height, h, is 11 m and the radius, r, is 5 m. Thus we have:

V = π(5 m)²(11 m), or

V = π(275) m³, or approximately 863.9 m³
