Question

The diameter of a circle is 8 cm. Find its area in terms of π.

Answer 1

Answer:

$16\pi$ $cm^2$

Step-by-step explanation:

Area of a circle is equal to $\pi r^2$, where r is the radius

$A=\pi r^2$

A diameter is twice the length of the radius. ($8/2$)

So the radius is 4 cm.

$r^2=4^2=16$

so the Area is $16\pi$
