Question

Find the volume of a cylinder with a diameter of 28 meters and a height of 8 and one half meters. Approximate using pi equals 22 over 7.

748 cubic meters
1,666 cubic meters
5,236 cubic meters
20,944 cubic meters

Answer 1

V = 5,236 m³\

Answer 2

V = 5,236 m³

Explanation:

the volume (V) of a cylinder is calculated as

V = πr²h ( r is the radius and h the height )

here diameter = 28 m , then r = 28m ÷ 2 = 14 m and h = 8
`(1)/(2)` m = 8.5 m , so

V =
`(22)/(7)` × 14² × 8.5

=
`(22)/(7)` × 196 × 8.5 ( cancel the 7 and 196 )

= 22 × 28 × 8.5

= 5,236 m³
