Question

A cylinder has a height of 20cm. The diameter of the cylinder is 3/ 5 its height. Calculate the volume of the cylinder in terms of π

Answer 1

Volume= πr^2h

Height= 20cm

Diameter = 3/5 × 20 = 12 cm

Radius = 12/2 = 6 cm

So, Volume= 22/7 × 6 × 6 × 20 = 15840/7 =262.8571428571cm^3

Answer 2

Step-by-step explanation:

height of cylinder = 20 CM

diameter of cylinder =

$20 \times \frac{3}{5} = 12cm$

Radius = 12/2. =6

$\: volume \: of \: cylinder \: = \pi \: r {}^{2} {h}^{}$

$\pi \: 6 \times 6 \times 20$

$720\pi \: \: answer$
