Find the area of a sector RST in circle S given that the radius of the circle is 3 inches and arc mRT = 30. Leave your answer in terms of pi. ​

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
