+283 Can someone please help me?
A sector of a circle has a central angle of 100 degrees. If the area of the sector is 250pi, what is the radius of the circle?
Thank you so much!
+1005 The formula for circle are is πr^2. You have 100/360 = 50/180 = 5/18 part of the area.
5/18 * πr^2 = 250π
5πr^2/ 18 = 250 π
5r^2/18 = 250
5r^2 = 250 * 18
r^2 =250*18/5 = 50*18 = 900
r = 30
