Question

1. find the circumference of the circle. use 3.14 for π. round to the nearest hundredth. 9.5 cm

Explanation:

Step1: Recall the formula for the circumference of a circle.

The formula for the circumference \( C \) of a circle is \( C = 2\pi r \) or \( C=\pi d \), where \( r \) is the radius and \( d \) is the diameter. Here, the radius \( r = 9.5 \) cm, so we can use \( C = 2\pi r \).

Step2: Substitute the values into the formula.

We know that \( \pi \approx 3.14 \) and \( r = 9.5 \) cm. So, \( C = 2\times3.14\times9.5 \).
First, calculate \( 2\times9.5 = 19 \). Then, multiply \( 19\times3.14 \).
\( 19\times3.14 = 59.66 \)

Answer:

The circumference of the circle is \( 59.66 \) centimeters.
