The radius of the circle is half of the diameter, so:
radius = 8/2 = 4 inches
The formula for the area of a circle is:
area = π × radius^2
where π (pi) is a constant approximately equal to 3.14.
Plugging in the radius:
area = 3.14 × 4^2 = 3.14 × 16 = 50.24 square inches
So the approximate area of the circle is 50.24 square inches.
