Question

A circular fountain has a diameter of 20 feet. which measurement is closet to the distance around the fountain?
a. 31.4 ft
b. 125.6 ft
c. 314 ft
d. 62.8 ft

Answer 1

To find the distance around the fountain, we need to calculate the circumference of the circle. The formula for the circumference \( C \) of a circle is:

\[
C = \pi \times d
\]

where \( d \) is the diameter. Given that the diameter of the fountain is 20 feet, we can plug that into the formula:

\[
C = \pi \times 20
\]

Using the approximate value of \( \pi \approx 3.14 \):

\[
C \approx 3.14 \times 20 = 62.8 \text{ ft}
\]

Thus, the measurement that is closest to the distance around the fountain is:

**d. 62.8 ft**
