Question

If radius of a sphere is 4cm, Find its surface area (π = 3.14)​

Answer 1

Step-by-step explanation:

area of sphere

$4\pi {r}^{2} = 4 \times 3.14\times {4}^{2} = 4 \times 3.14 \times = 4 \times 4 = 200.96 {cm}^{2}$

Answer 2

Answer:

r= 4cm

surface area of sphere is 4π R2

Step-by-step explanation:

4*3.14*4*4=200.96 ans
