A circular ice rink is being built in town. Around the ice rink, a walkway will be built. The ice rink will have a diameter of 80 feet and the walkway will be 10 feet wide. What is the approximate area of the walkway?

so the ice rink diameter is 80 feet what mean that the radius of ice rink is 40 feet the walkway is 10 feet wide so 10+40=50 what mean that the radius and the walkway wide make 50 feet length together
using this length area = pi*r^2 = 3,14*(50)^2 = 7850 feet squared
area of ice rink = 3,14*40^2 = 5024 feet squared

area of the walkway = 7850-5024 = 2826 feet squared

hope helped
