Question

what is the area of a circle with a radius of 3m

Answer 1

Area of circle=πr²
where, π=22/7 or 3.14
r=radius of circle
r=3m
Area=(3.14*3*3)m²
=28.26m²

Answer 2

Answer:

The area of the circle is 28.26 m².

Concept:

Area of a circle:

Let a circle be there with center O and radius r m. Its area is given by,

A = π r²

where A = Area of the circle

π = A constant whose value is (22/7) or 3.14

r = Radius of the circle.

Given:

The radius of the circle, r = 3 m

Find:

The area of the circle.

Solution:

Radius of the circle, r = 3 m

Area of the circle is given by,

A = π r²

A = π(3)²

A = π × 3²

A = π × 9

A = 9π

Putting π = 3.14, we get

A = 9(3.14) m²

A = 28.26 m²

Hence, the area of the given circle is A = 28.26 m².
