Which best represents the circumference of a circle with a radius of 12 inches?

A. 80 inches
B. 75 inches
C. 68 inches
D. 38 inches

Answer :

Final answer:

To find the circumference of a circle with a 12-inch radius, use the formula C = 2πr, resulting in approximately 75.4 inches, making 75 inches the closest answer.

Explanation:

The question is about finding the circumference of a circle with a radius of 12 inches. To calculate the circumference (C), we use the formula C = 2πr, where π (Pi) is approximately 3.1416 and r is the radius of the circle. Plugging in the radius of 12 inches, the equation becomes C = 2 × 3.1416 × 12, which equals approximately 75.4 inches. Therefore, the option that best represents the circumference of this circle is 75 inches.

Answer:

The circumference is 75 inches

Step-by-step explanation:

To solve this we have to use the formula to calculate circumference of a circle

c = circumference

π = 3.14

r = radius = 12in

c = π * 2r

We replace with the values ​​we know

c = 3.14 * 2 * 12in

c = 75.36 in

The circumference is 75in
