He needs to make a large circular wooden clock that measures about 6 feet in circumference. Write an equation he can use to find r the radius of the clock

Answer 1

C = pi * r^2
6 = 3.14 * r^2
6 - 3.14 = r^2
2.86 = r^2
1.69 = r

Answer 2

C = 2pi*r = 6,
2*3.14*r = 6,
6.28r = 6,
r = 6 / 6.28 = 0.96 ft.
