Question

Find the area of the circle. Leave your answer in terms of pi.

The diameter shown is half of a radius, being 2.4. I've tried everything, but I don't seem to get the right answer.

Answer 1

The area of circle is 1.44π m²

Explanation:

It is given that the diameter of circle is 2.4m. In order to find the value of radius, you have to divide diameter by 2. Then using the formula of the area of circle, A = π×r² where r is the radius :

diameter = 2.4m

radius = 2.4 ÷ 2

= 1.2m

A = π × 1.2²

= 1.44π m²
