What is the approximate diameter of a tire that will make 775 complete rotations in one mile? (Note: there are 5280 feet in 1 mile)

About 2.17 feet.

Step-by-step explanation:

Let d represent the diameter of the tire.

Then the circumference of the tire will be:

So, the tire will travel dπ miles after one rotation.

After 775 rotations, the total miles traveled should be 5280 feet. Thus:

Solve for d:

Approximate:

The circumference of the tire should be about 2.17 feet.

x=12 units bd= 10 units

step-by-step explanation:

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
