Question

use the information given to answer the question. consider the circle with a diameter of 42 millimeters. what is the approximate circumference of the circle, rounded to the nearest hundredth of a millimeter? (use 3.14 as an approximation of pi.)

Explanation:

Step1: Recall the formula for circumference

The formula for the circumference of a circle is $C = \pi d$, where $C$ is the circumference and $d$ is the diameter.

Step2: Substitute the given values

Given $d = 42$ mm and $\pi\approx3.14$, we substitute into the formula: $C=3.14\times42$.

Step3: Calculate the product

$3.14\times42=(3 + 0.14)\times42=3\times42+0.14\times42=126 + 5.88 = 131.88$ mm.

Answer:

131.88 millimeters
