Question

calculate the volume of the hemispherical dome if the height of the dome is 21 m ​

Answer 1

Given,

Height of a hemispherical dome = 21 m

To find,

The volume of the hemispherical dome.

Solution,

We can simply solve this mathematical problem using the following process:

As per mensuration;

The volume of a hemisphere = 2/3π(radius)^3

Now, according to the question;

Height of the hemispherical dome

= radius of the hemispherical dome

= 21 m

Now, the volume of the hemispherical dome

= 2/3π(radius)^3

= 2/3 × 22/7 × 21 × 21 × 21

= 19,404 m^3

Hence, the volume of the hemispherical dome equals 19,404 m^3.
