Answer:
A=133 A=71.5 A=31.5 A=1
Step-by-step explanation:
The area of a circle is pi*r^2.
The angles in a circle add up to 360 degrees.
Let's say I have a circle with radius 2.
The total area of the circle is pi* (2^2) = 4pi
Let's say I cut out 15 degrees of this circle. This piece is 15 out of 360 of the whole circle.
The area of this part is (15/360) * 4pi
The rest of the area is (360-15)/360 * 4pi.
I hope this helps.
