Question

The measurement around the widest part of these holiday bulbs is called their circumference. The formula for circumference is 2x (r) and r is the radius of the circle. Suppose the radius of a given circle is 1.25 inches. Find the circumference of this circle.

Answer 1

To calculate the circumference of a circle with a radius of 1.25 inches, use the formula C = 2πr, which gives a circumference of 7.853975 inches.

Step-by-step explanation:

To find the circumference of a circle when given the radius, you can use the formula C = 2πr where π (pi) is approximately 3.14159 and r is the radius of the circle. In this case, the radius is given as 1.25 inches. By substituting the value of the radius into the formula, we get:

C = 2 × 3.14159 × 1.25 inches

C = 2 × 3.14159 × 1.25

C = 7.853975 inches

Therefore, the circumference of the given circle is 7.853975 inches.
