Question

Dave designed a circular pool with a diameter of 24 meters. What is the area of the bottom of the pool round the nearest tenth

Answer 1

450 m²

Explanation:

Area of a circle:
`\pi r^(2)`

r is radius and we need to divide the diameter value by 2 to obtain the radius

= 24 / 2 = 12m

Area of a circle =
`\pi * 12^(2)`

= 452.57

≈ 450 m²
