What is the area of the half circle below?2 Pi 4pi 8pi 16pi

Reika [66]

Answer:

A = 8π cm²

Step-by-step explanation:

The area (A) of a circle is calculated as

A = πr² ( r is the radius )

Here diameter = 8 , then r = 8 ÷ 2 = 4

The area of half a circle is then

A = $\frac{1}{2}$ π × 4² = $\frac{1}{2}$ × π × 16 = 8π cm²
