Question

if the surface area of a sphere is 1386 cm square. , find its volume.
please give me answer..........
please... ​

Answer 1

Required volume of the sphere = 4849.05 cm³ approx.

Answer 2

Answer:

4846.59‬ cm³

Step-by-step explanation:

Given :

Surface area of sphere = 1386

i.e. 4 π r² = 1386 cm²

r² = 1386 × 7 / 88

r = √ 110.25‬

r = 10.5 cm

Now :

Volume of sphere = 4 / 3 π r³

Volume of sphere = 4 / 3 × 22 / 7 × 10.5³ cm³

Volume of sphere = 4 / 3 × 3.14 × 10.5 × 10.5 × 10.5 cm³

Volume of sphere = 4846.59‬ cm³

Hence we get answer.
