Answer 1

Answer:c

Step-by-step explanation:

SA of sphere=4πr2

=4×22×2.5×2.5/7

=78.5cm2

Answer 2

Step-by-step explanation:

Given That;

The radius of the sphere is= 5 cm

The surface area of the sphere=?

We know that;

The surface area of a sphere$=4\pi r^2$

Then the surface area of the given sphere is;

$4\pi (5)^2=4(3.142)(25)$

           $=314.2$

Therefore our final answer is 314.2 $cm^2$ (c)
