Answer 1

Hello Nidhidevrani !

Answer:

1386 cm²

Step-by-step explanation:

Given :

Radius of a circle = 21 cm

π = 22/7

Formula :

Area of a circle = πr² units²

• Where r is the radius of the circle.

Procedure :

A = π(21)² cm²

⇒ A = (22/7) × (21) × (21) cm²

⇒ A = 22 × 3 × 21 cm²

∴ A = 1386 cm²
