Question

I need help. I have no idea on this question

Answer 1

$C=18.84\text{ ft}$

Explanation

the circumference of a circle is given by:

$C=\pi\cdot diameter$

Step 1

find the diameter of the larger fountain:

the diameter of the larger fountain is the sum of the small ones, so

$\begin{gathered} \text{Diameter=}3\text{ ft +3 ft} \\ \text{Diameter}=6\text{ ft} \end{gathered}$

Step 2

replace the diameter in the formula

$\begin{gathered} C=\pi\cdot diameter \\ C=\pi\cdot6\text{ ft} \\ C=18.84\text{ ft} \end{gathered}$

I hope this helps you
