Question

find the circumference of a circle with a radius of 7 centimeters. use 3.14 as an approximation for \\(\pi\\). round your answer to the nearest whole centimeter. enter only the number. the solution is \\(\square\\)

Explanation:

Step1: Recall circumference formula

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

Step2: Substitute values

Given \( r = 7 \) cm and \( \pi \approx 3.14 \), substitute into the formula: \( C = 2\times3.14\times7 \).

Step3: Calculate the product

First, calculate \( 2\times3.14 = 6.28 \), then \( 6.28\times7 = 43.96 \).

Step4: Round to nearest whole number

Rounding \( 43.96 \) to the nearest whole number gives \( 44 \).

Answer:

44
