Question

Find the volume of the cylinder in which diameter is equal to 70 cm and height is equal to 20 metre

Answer 1

volume =?

diameter = 70 cm

radius = d/2

= 70/2

=35

height= 20 m = 2000cm

now

volume of cylinder =

.

22/ 7 × 35 ×35×2000

22× 5×35×2000

= 7700000 cm

= 7.7 m cube

${7.7}^{3?}$

Answer 2

The volume of the cylinder in which diameter is equal to 70 cm and height is equal to 20 metre is $7700000 cm^2$

Step-by-step explanation:

Diameter of cylinder = 70 cm

Radius of cylinder =$\frac{70}{2} = 35 cm$

Height of cylinder = 20 m = 2000 cm

Volume of cylinder =$\pi r^2 h$

Volume of cylinder =$\frac{22}{7}(35)^2(2000)$

Volume of cylinder = $7700000 cm^2$

Hence the volume of the cylinder in which diameter is equal to 70 cm and height is equal to 20 metre is $7700000 cm^2$
