Question

find the actual area and the actual perimeter of each shaded region. This means leave the answer
in terms of pie; do not round it....the circle has an angle with a 60 degree hsaded region and a 12 line inside

Answer 1

what is a 12 line? do you mean the radius of the circle is 12?

Answer 2

The area of a sector is: pi*r^2 *(angle in degrees/360)
The perimeter of a sector is the arc length plus 2*radius; arc length is (angle in radians*radius) so the equation is (angle in radians)*r + 2*r

Answer 3

that should give you the area and perimeter of the sector

Answer 4

think this would be straightforward with a picture
