Question 944572
A sector of a circle with a radius of 6 cm has a central angle of 90º.
 What is the area of the sector, in square centimeters? 
Express your answer in terms of π.
:A = {{{1/4}}} * {{{pi*6^2}}}
There are 4 90degree sectors in a circle, therefore the area of the sector
A = {{{1/4}}} * {{{pi*6^2}}}
A = {{{1/4}}} * {{{36*pi}}}
A = {{{9*pi}}} sq/cm
