Answer:
r = 32inches
Step-by-step explanation:
to find the radius of a circle whose circumference is 64pi inches
with unknown radius
using the fomular for finding the circumference of a circle
mathematically.
the circumference of a circle = 2πr
note the of π = 3.142
the circumference of a circle = 2 × π× r
64π= 2πr
divide both sides by 2π
64π/2π = 2πr/2π
32 = r
r = 32inches
therefore the radius of the circle is 32inches
