Question

A cylinder has a base diameter of 14m and a height of 15m. What is its volume in

cubic m, to the nearest tenths place?

Answer 1

2310m^3

Explanation:

base area which is the circle = πr^2

But diameter, d = 14, r = 14/2 = 7

area = π × (7)^2 = 22/7 × 49 = 22 × 7 = 154

Volume = base area × height

= 154 × 15 = 2310

Answer 2

2309.1
