Answer 1

Question:-

Find the surface area of the sphere in terms of π 7 yd.

Solution:-

We know,

`\dag` Formula of Surface area of the sphere is 4πr².

Radius (r) = 7 yd (Given)

Now,

Surface area of the sphere = 4 × π × (7)²

Surface area of the sphere = 4 × π × 7 × 7

Surface area of the sphere = 196π sq. yd.

The surface area of the sphere is 196 sq. yd. [Answer]
