Question

find the circumference of the circle. use 3.14 for π. round to the nearest hundredth, if necessary.
7.5 in.
the circumference of the circle is about inches.

Explanation:

Step1: Recall the formula for circumference

The formula for the circumference \( C \) of a circle is \( C = 2\pi r \), where \( r \) is the radius.

Step2: Identify the radius

The radius \( r \) is given as \( 7.5 \) inches.

Step3: Substitute values into the formula

Substitute \( \pi = 3.14 \) and \( r = 7.5 \) into the formula: \( C = 2\times3.14\times7.5 \)

Step4: Calculate the result

First, calculate \( 2\times3.14 = 6.28 \). Then, \( 6.28\times7.5 = 47.1 \)

Answer:

47.1
