Question

the surface of area is 3844 m square find the radius of sphere​

Answer 1

Answer:

surface area of sphere =4πr^2.

3844=4πr^2

3844/4=πr^2

961/π= r^2

961*7/22=r^2

305.77=r^2

√305.77=r

17.48=r

Answer 2

Answer:

$area \: of \: sphere = {4πr}^{2}$

so..

3844=4πr^2

√3844=4πr

62=4πr

62÷4=πr

15.5=3.14×r

15.5÷3.14=r

4.93630573=Radius
