## anonymous one year ago What is the approximate circumference of a circle with a radius of 40 inches? Use π ≈ 3.14. A. 125.6 inches B. 251.2 inches C. 502.4 inches D. 5024 inches

1. ybarrap

$$C=2\pi r$$ Plug in the value for radius, r ,and calculate.

2. ybarrap

Approximate $$2\pi$$ as just 6.
