Answer:
62.83 in
Step-by-step explanation:
C is circumference
r is the radius
We sum up both, given first one radius is 2 and second one radius is 8, so we have:
The length of the belt should be around 62.83 in
Answer:79.5
Step-by-step explanation:
you would divide 23.85 by 3 to get the answer for one and then multiply it by 10
Answer: The answer, rounded to the nearest tenth, is 113.0
Step-by-step explanation:
This is the formula for calculating the circumference of a circle:
C= 2pi r
R is the radius. Since the path is 2 feet wide, we can add 2 to the radius of the garden to get the radius of the whole path and garden.
2+4=6 so the radius for the total area of the garden and path is 6 feet.
Now we need to plug 6 into the formula to find circumference.
