Asked by Shreya

A circular park of 28 m diameter has been constructed. A 3.5m circular track outside has been developed along the park. Using algebric formulae, find the area of the track around the park.
Answered by Damon
subtract area of inside circle from area of outside circle

radius inside = 28/2 = 14
radius outside = 14+3.5 = 17.5

so
pi(17.5^2-14^2)
