Answer:

615.44 mm²

Explanation:

Before finding the area of the circle, first, let us find the radius of the circle.

Given that,

diameter ⇒ 28 mm

Therefore,

d = 2r

28 = 2r

Divide both sides by 2.

14mm = radius

And now, let us find the area.

The formula to find the area of the circle is :

Area = π r²

Let us solve now.

Area = π r²

= 3.14 × 14 × 14

= 43.96 × 14

= 615.44 mm²
