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

kolezko [41]

Answer:

450 m²

Step-by-step 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
