a trampoline measures 7 feet from the center to the outer edge. what is the circumference of the trampoline?
a .43.9 feet
b. 11 feet
c. 22 feet
d. 87.9
c. 22 feet
To calculate the circumference of a circle, you use the formula C = 2πr, where r is the radius of the circle. In this case, the radius of the trampoline is 7 feet, so the circumference would be:
C = 2π(7)
C = 14π
C ≈ 22 feet
