Question

Find the surface area of a sphere whose volume is 606.375 m.​

Answer 1

Answer:

We know that

Volume of the sphere = 4/3 πr3

By substituting the values

606.375 = 4/3 × (22/7) × r3

On further calculation

r3 = (606.375 × 3 × 7)/ 88

So we get

r3 = 144.703125

By taking cube root

r = 5.25m

We know that

Surface area of the sphere = 4 πr2

By substituting the values

Surface area of the sphere = 4 × (22/7) × 5.252

So we get

Surface area of the sphere = 346.5 m2

Therefore, the surface area of the sphere is 346.5 m2.
