Arectangular skate park is 60 yards long and 50 yards wide

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,

mrb

it's undefined because anything multiplied by 0 is 0. that said, 7 days is 168 hours
