The floor of a skating rink is circular and has a radius of 14 meters. what is the
area of the floor?

A=pi(radius^2)
3.14(14^2)
Area= 615.75 square meters

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
