Find the circumference of the circle to the nearest foot.
42 ft
A. 132 ft
B. 264 ft
C. 1,320 ft
D. 2,640 ft
B. 264 ft
The formula to calculate the circumference of a circle is C = 2πr, where π is approximately 3.14 and r is the radius of the circle. In this case, the radius is half the diameter, which is given as 42 ft. So, the radius (r) is 42/2 = 21 ft.
Now, substituting the values into the formula, we have C = 2π(21).
Using the approximation of π as 3.14, we can calculate the circumference as C = 2 * 3.14 * 21 = 132.36 ft.
Rounding this to the nearest foot, the circumference of the circle is approximately 132 ft.
The answer is A. 132 ft.
