Question

1. a circular fountain has a diameter of 10 meters. what is the circumference of the fountain?

a. 5π meters
b. 10π meters
c. 20π meters
d. 100π meters

Explanation:

Step1: Recall the formula for the circumference of a circle

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

Step2: Substitute the given diameter into the formula

We are given that the diameter \( d = 10 \) meters. Substituting this into the formula \( C = \pi d \), we get \( C=\pi\times10 = 10\pi \) meters.

Answer:

b. \( 10\pi \) meters
