The circumference of a circle can be found with this equation:
C = 2r
"r" is the radius, which is half of the diameter.
The diameter is 20.
20 ÷ 2 = 10
Your radius is 10. Now that you know the radius, you can plug it into the equation:
C = 2r
C = 2(10) Multiply 2 and 10 together
C = 20
Your circumference is:
20 inches or 62.8318530718 inches(you should round it if you want lol)
we are given
The scale is
the distance from Happy Hill Park to Rainbow Valley Park is 4 1/2 inches
we can change it into rational form
and we get
so, we can multiply both sides by 9
now, we can simplify it
so, the actual distance between the two parks is 27 miles........Answer
