Question

A circle is cut in half and removed. What is the approximate area (shaded region) of the remaining portion of the circle in square feet? There is a picture of a circle with a line through the middle showing 12 feet.

12 feet ( A=pie(3.14)r^2)
Options are: A. 60 ft2 B. 120 ft2 C. 225 ft2 D. 450 ft2
​

Answer 1

Explanation:

area of a whole circle is pi
`r^(2)`

diameter is 2*r

1/2 * pi *
`6^(2)` will find the area of 1/2 of the circle that has a diameter of 12'

56.54866 '

so approx 60 ft
