Answer:
The perimeter of a circle is calculated with 2πr
The r stands for radius. The radius is half of the diameter.
So r=2.25
Plug it in 2π(2.25)
It was simplify to 4.5π
Which would simplify down to 14.14 miles rounding to the nearest hundredth.
Answer:
Step-by-step explanation:
Given radius
and arc length
.
2x+2=-52
2x=-54
x=-27
That is the simple formula for it.
