Complete the table by finding the circumference and area of a circle with a radius of 3 feet. Substitute 3.14 for pi. Express your answer in the tenths place.
Radius Circumference Area
3ft. ? ft. ?ft.^2
Radius Circumference Area
3ft. 18.8 ft. 28.3 ft.^2
To find the circumference of a circle, the formula is 2 * π * r, where r is the radius.
Circumference = 2 * 3.14 * 3 = 18.8 ft
To find the area of a circle, the formula is π * r^2.
Area = 3.14 * 3^2 = 28.3 ft^2
