Answer:
r = 4.5 ft
Step-by-step explanation:
The distance around a circle is known as the circumference. The formula for the circumference of a circle is denoted as 2πr.
circumference of a circle = 2πr
where
r = radius
π = 3.14
circumference = 28.26 ft
28.26 = 2 × 3.14 × r
28.26 = 6.28r
divide both sides by 6.28
r = 28.26/6.28
r = 4.5 ft
