Question

Find the volume of right circular
cylinders whose radius and
height
are 8cm and 40cm.
respectively​

Answer 1

Answer:

$\tt \: Volume \: of \: \: right \: circular \: cylinder =\pi {rh}^{2}$

$= \bf \frac{22}{7} \times 8 \times 8 \times 40 \\ = \tt\frac{22}{7} \times 2560 \\ = \bf\frac{56320}{7} \: \: \: or \: \: \: 8045.71$

Answer 2

Answer :

• Volume of cylinder is 8045.48cm³

Given :

• Radius of cone (r) = 8cm
• Height of cone (h)= 40cm

To Find :

• Volume of cylinder

Solution :

✰ Here in the Question we are given Radius and Height of cone. We know that Volume of cone is πr²h. By, putting the value in the formula we can easily find the Volume of Cone.

Volume of cylinder = πr²h

→ Volume of cylinder = 22/7 × (8)² × 40

→ Volume of cylinder = 22/7 × 64 × 40

→ Volume of cylinder = 56320/7

→ Volume of cylinder = 8045.48cm³

∴ Volume of cylinder is 8045.48cm³

More Formulae :

• Volume of cube = (Side)³

• Volume of cubiod = L × B × H

• Volume of cone = 1/3πr²h

• Volume of Sphere = 4/3πr³

• Volume of Hemisphere = 2/3πr³
