Question

If the CSA of hemisphere is 2800 cm square. Find its volume?

Answer 1

Answer:

Step-by-step explanation:

We know that

CSA of a hemisphere is 4(pi)r^2

4(pi)r^2=2800

=>(pi)r^2 = 700

=>r^2=700×3.14

=>r = (700×3.14)^1/2

=>r=46.88(approx.)

Therefore volume of the sphere is

2/3(pi)r^3

=215675.69(approx.)
