Question

Circumference of circle is 6 pi cm, it’s area is

Answer 1

Step-by-step explanation:

Circumference = 6π

2πr = 6π

= 2r = 6

r = 3 cm

Area of Circle = πr²

= π × 3²

= 9π cm²

Answer 2

Given that :-

• 1. Circumference of circle is 6 pi cm

To find :-

• 1. Area of the circle.

Solution :-

Circumference of a circle = 2πr

Area of Circle = πr²

Solution :-

Circumference of circle = 2πr

⇒ 6π = 2πr

⇒ r = 6π/2π

⇒ r = 3

Area of Circle = πr²

Area of Circle = π × 3 × 3

Area of Circle = 9π cm.

Hence,

The Area of Circle is 9π cm.
