E.15.7
F.31.4
G.49.3
H.78.5

Answer 1

Answer:

F.  31.4 ft

Step-by-step explanation:

The distance around the edge of a circle is called the circumference.

Formula for the circumference of a circle

$\sf Circumference\:of\:a\:circle=2 \pi r$

(where r is the radius)

Given values:

• radius = 5 ft
• π = 3.14

Substitute the given values into the formula:

$\begin{aligned}\implies \sf circumference & = \sf 2 \cdot 3.14 \cdot 5\\ & = \sf 31.4\:ft \end{aligned}$

Therefore, the distance around the edge of the circular patio is 31.4 ft.
