Question

the formula for finding the circumference of a circle is c = π × d where c is the circumference and d is the diameter. use 3.14 as an estimate for π. what is the circumference of a circle with a diameter of 10 inches? a. 13.14 inches b. 15.70 inches c. 31.40 inches d. 78.50 inches

Explanation:

Step1: Identify formula and values

The formula for the circumference of a circle is $C=\pi\times d$. Given $d = 10$ inches and $\pi=3.14$.

Step2: Substitute values into formula

$C=3.14\times10$.

Step3: Calculate the result

$C = 31.4$ inches.

Answer:

C. 31.40 inches
