Question

find the surface area and volume of sphere whose radius is
5.6cm​

Answer 1

Answer:

394.24cm²

Step-by-step explanation:

Given, radius r=5.6 cm.

We know, the surface area of a sphere of radius r=4πr^2    

=4×  7 /22 ×5.6×5.6

=394.24cm^2

Answer 2

Answer:

surface are of sphere = 4πr²

putting in formula,

4×22/7×5.6×5.6

=394.24cm²

Step-by-step explanation:

volume of sphere = 4/3πr³

using formula,

4/3×22/7×5.6×5.6×5.6

volume = 735.91cm³
