Question

surface area of a sphere of radius 10 centimetre is_______.

Answer 1

4 x pi x 10 x 10=1256 cm^2

the surface area of sphere is 4 x pi x r x r

use this

Answer 2

Answer:

Step-by-step explanation:

Surface area of a sphere= 4×pi×r^2

Here pi=3.14 and r (radius)=10cm

Area=4×3.14×10^2

=4×3.14×100

=1256cm^2
