Its radius is 4.8 cm, rounded to the nearest tenth.
Radius is the square root of (71/pi) = 4.8 feet rounded to the nearest tenth

Circumference circle = pi* r^2 Load and crunch previous formula was for area. The correct answer is 2*Pi*r = 24*Pi = 75.4 cm (rounded to nearest tenth). I stand corrected. One needs be more careful. Thank you.

The area of a circle to the nearest tenth if its radius is 4.5 is: 63.6 square units.
Circumference of the circle: 48*pi = 150.8 inches rounded to the nearest tenth
2*radius*pi or diameter*pi, pi = 3.14 (rounded to the nearest tenth)
The circumference of a circle that has a diameter of 34 inches rounded to the nearest tenth is 106.8 inches.
