Question 756429: HELP me please
A large pizza at shae is baked on a circular pizza pan with 12 inch diameter and is cut into 8 equal slices.When one slice of pizza is removed from the pan,a sector of the pan is visible.
Determine:
a) the degree and radian measure of the central angle of this sector
b)the peremieter of the esector
c)the area of the sector

dia is 12" so radius= 6"=r
cut into 8 equal slices so
a)the angle is 360deg/8=45 deg=45*pie/180 rad [as 180deg=pie rad]
=pie/4 rad
b)perimeter of the sector=r+r+1/8*perimeter of the circle
=2r+2pie r/8=2r+pie r/4=2*6+3.414*6/4=17.121"
c)area=1/8*area of the circle=pie/8*r^2=pie/8*6^2=14.14 in sqrd
