Answer:

16П or approximately 50.3)

Explanation:

The area of a circle is equal to П*r²

Since the circle is inside a rectangle with side that is equal to 8, we know that d = 8

2r = d

r = 8/2

r = 4

A = П*r²

A = П*16

А = 16П ( or 16*3.141592653589793238... = 50.26548... ≈ 50.3)

Answer:

area = 50.27
cm^2

Explanation:

In the diagram, we see that the diameter of the circle is 8cm. Therefore the radius of the circle is 8/2 = 4cm.


area \hspace{0.15cm}of \hspace{0.15cm}circle = $\pi$r^2

= π
(4)^2

= 50.27
cm^2
