Question

The tank on a petrol lorry is a cylinder 2m in diameter and 7cm long

a. Calculate its volume in m3.
b. Find its capacity in kilolitres
​

Answer 1

Answer: 0.22 kilolitre

Explanation:

First, let’s find the volume of the tank. We know the volume of a cylinder is represented by the equation V=πr^2h,

Radius = 1 m

Height = 7 cm = .07 m

The tank is 0.22 cubic meters

Now that we found the volume, we will try to find how many liters are in the tank.

1 cubic meter = 1 kilolitre

So, 0.22 cu. m = 0.22 kilolitre
