Question

Calculate the surface area of a hemispherical dome of a temple with diameter 35 m to be

whitewashed from outside.​

Answer 1

Step-by-step explanation:

Here, radius of hemispherical dome (r) = 14 m 

Surface area of dome = 2πr2

= 2 × 22 / 7 × 14 × 14 = 1232 m2 

Hence , total surface area to be whitewashed from outside is 1232 m2     

Answer 2

Answer:

Step-by-step explanation:

Here, diameter of hemispherical dome (D) = 14 m  

Surface area of dome = πd2

=  22 / 7 × 35 x 35 = 3580 m2  

Hence , total surface area to be whitewashed from outside is 3580 m2
