Question 891639
if te area of the circle is 72sq,m,then what percentage of area of circle is coverd by sector
given angle in sector is 135'
***
area of circle=πr^2=72
r^2=72/π
area of sector=1/2r^2theta, r=radius, theta in radians
135˚=135π/180 radians
area of sector=1/2*72/π*135π/180=36*135/180
area of sector/area of circle=(36*135/180)/72=.375=37.5%
