Question

A skateboard’s wheel has a radius of 55 millimeters. What is the area of the wheel ?

Answer 1

Answer:

3025π

Step-by-step explanation:

A skateboard’s wheel is a circle and we need to work out the area of the skateboard’s wheel so we have utilise the formula π × r² where 'r' is the radius. So lets substitute in the values into the formula of finding out the area of the skateboard's wheel.

Area of skateboard's wheel = π × r²

→ Substitute in the values

Area of skateboard's wheel = π × 55²

→ Simplify

Area of skateboard's wheel = 3025π

Answer 2

Answer:

Step-by-step explanation:

$A=\pi r^2=\pi *55^2$ ≈ $9503.31778mm^2$
