Question

If a circle has a radius of 6 inches, what is the circumference rounded to the nearest whole

number? (Use i = 3.14.)
A) 38 in.
[B] 19 in.
[C] 113 in.
[D] 76 in.

Answer 1

Using the formula C = 2πr, the circumference of a circle with a radius of 6 inches is 37.68 inches, which rounds to 38 inches, making option [A] the correct answer.

Step-by-step explanation:

If a circle has a radius of 6 inches, the circumference can be calculated using the formula C = 2πr, where π (pi) is approximately 3.14. Plugging in the radius (r = 6 inches) into the formula gives us:
C = 2 × 3.14 × 6 inches
C = 37.68 inches
When rounded to the nearest whole number, the circumference of the circle is 38 inches. Therefore, the correct answer is [A] 38 in.
