Question

The circumference of a circle is 149 mm.

Answer 1

Answer:

Step-by-step explanation:

The formula to find the circumference of a circle is :

C = 2 π r

Given that, the circumference of the circle is 149 mm.

First, let us find the radius of the circle.

C = 2 π r

149 = 2 × 3.14 × r

149 = 6.28r

Divide both sides by 6.28.

23.72 = radius

Now let us find the area of the circle.

The formula to find the area of the circle.

A = π r²

Let us find it now.

A = 3.14 × 23.72²

A = 3.14 × 562.6384

A = 1766.7mm²
