Question

solve each of the following real - world problems.

1. colton is buying a hula hoop at the store. the circular hoop he finds has a diameter of 50 inches. what is the total circumference of the hula hoop? round your answer to the nearest tenths place.

Explanation:

Step1: Recall the formula for circumference

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

Step2: Substitute the given diameter

Given \(d = 50\) inches, substitute into the formula: \(C=\pi\times50\).

Step3: Calculate the value

Using \(\pi\approx3.14159\), \(C = 3.14159\times50=157.0795\).

Step4: Round to the nearest tenths

Rounding \(157.0795\) to the nearest tenths (one - decimal place), we look at the second decimal digit. Since \(7\geq5\), we round up. So \(157.0795\approx157.1\).

Answer:

\(157.1\) inches
