Question

1. find the diameter of a circle with a circumference of 27 centimeters. use 3.14 for π. round to the nearest tenth.

Explanation:

Step1: Recall the formula for the circumference of a circle

The formula for the circumference \( C \) of a circle is \( C=\pi d \), where \( d \) is the diameter. We need to solve for \( d \), so we can rearrange the formula to \( d = \frac{C}{\pi} \).

Step2: Substitute the given values into the formula

We know that \( C = 27 \) centimeters and \( \pi=3.14 \). Substituting these values into the formula \( d=\frac{C}{\pi} \), we get \( d=\frac{27}{3.14} \).

Step3: Perform the division and round to the nearest tenth

Calculating \( \frac{27}{3.14}\approx8.6 \) (rounded to the nearest tenth).

Answer:

The diameter of the circle is approximately \( 8.6 \) centimeters.
