Answer:

16π square inches

Explanation:

We know the relation between diameter and radius of the circle is that a diameter if half a radius so the diameter halved will give us the radius so, 8 ÷ 2 = 4. The radius of the circular picture is 4 inches and we have to utilise and important formula, the area of a circle which is

→ π × r²

⇆ We have to substitute in the values of the radius so

→ π × r²

⇆ Substitute in the values

→ π × 4²

⇆ Simplify

16π

We can see that all the answer options are in π format so we don't convert the answer so the area of the circular picture is 16π square inches
