Question

Calculate the surface area of a hemispherical dome of a temple with radius 14m to be white washed from outside

Answer 1

Hi ,

Let the radius of the

hemispherical dome ( r ) = 14 m

We know that ,
___________________________

Surface area of the hemispher =

A = 2 × pi × r^2

___________________________

A = 2 × ( 22 / 7 ) × ( 14 )^2

= 2 × ( 22 / 7 ) × 14 × 14

= 1232 m^2

Therefore ,

Curved surface area of the

hemispherical dome = 1232 m^2

I hope this helps you.
