# The surface area

Answer :

Given: The surface area of a sphere is 154 cm2.

TSA of the sphere is given by: 4 × π × r2

4 × π × r2 = 154

r2 = 154 × = r2 = r = r = Now, Volume of hemisphere is given by: πr3

Let V be the Volume of the hemisphere

V = × π × r3

V = × π × ( )3 = cm3 = 179 cm3

V = 179 cm3

That is Volume of the given sphere is 179 cm3
