Question

8) The surface area of a sphere of radius 35 cm is
a) 153 cm
c) 155 cm
b) 154 cm
d) 156 cm​

Answer 1

Answer:

• Surface area of the sphere having radius of 35cm is 15400cm² ✔

Step-by-step explanation:

Surface area of a sphere is given by :

→ 4πr²

We have,

→ r (radius) = 35cm

→ π = 22/7

So, surface area of the sphere is :

→ 4 • 22/7 • (35)²

→ 4 • 22/7 • 35 • 35

→ 4 • 22 • 5 • 35

→ 88 • 175

→ 15,400cm²
