Question

0-1 Find the volume of right
circular cylinder whose:
1.R = 2.8m,H=15m
2.R=3.5cm,H=40cm
3.R=0.35m,H=1.25m​

Answer 1

Formula

$\pi {r}^{2} h$

1. r=2.8 m, h=150 m

= 22/7 x 2.8 x 150

= 3694.51 m³

2. r=3.5 cm, h=40 cm

= 22/7 x 3.5 x 40

= 1539.38 cm³

3. r=0.35m, h=1.25m

= 22/7 x 0.35 x 1.25

= 0.48 m³
