Question

.Find C.S.A of a sphere whose radius is 14 cm​

Answer 1

Step-by-step explanation:

Solution. Therefore, the surface area of a sphere having radius 14 cm is 2464 cm2.

Answer 2

ANSWER

CSA of sphere =$4$$\pi$$r^{2}$

where is the radius of sphere

so, r = 14 cm

$\pi =$ 22/7

so according to formula

CSA = 4$*$22/7$*$$14^{2}$

= 4*22*2*14

= 88*28

= 2464 $cm^{2}$
