Calculate the arc length of a sector of a circle with a radius of 7 and central angle measure of 98 degrees. Then, calculate the area of the sector.
***
arc+length%3As=r%28theta%29
area%3AA=%281%2F2%29r%5E2%28theta%29
r=radius
%28theta%29+in+radians
98˚=98*π/180 radians
..
arc length=7*98π/180≈11.97units
area=(1/2)(7^2)98*π/180=41.9 sq units
