Question

If the diameter of the circle is 24 cm, find its area correct to one decimal place.

A= ______ cm2

Answer 1

A=pi times radius squared

24/2= 12 is the radius (since it's half of diameter)

A=pi times 12 squared

12 squared is 12 times 12 which is 144

A=pi times 144

A=452.389342

Rounded to 452.4
