Question

find the surface area of sphere of radius 7cm​

Answer 1

$\huge\bf{SoLutiOn:-}$

Given that :-

→ radius = 7cm

Find out :-

→ Surface area of sphere

Then according to questions;-

using formula ,

$\boxed{\boxed{\boxed{\tt{\green{Surface \:area \:of\: sphere\: = 4\pi{r}^{2} } }}}}$

Surface area of sphere = 4 × π × 7 × 7

Surface area of sphere = 4 × 22/7 × 7 × 7

Surface area of sphere = 4 × 22 × 7

Surface area of sphere = 616cm²

Answer 2

Answer:

Step-by-step explanation:

4*pi*r^2

=4*22/7*7*7

=88*7

=616cm.sq
