The circumference of the tire would be: 28 x PI = 87.96 inches = 88 inches.
88 inches / 12 inches = 7.33 feet
Every revolution the tire would travel 7.33 feet.
1 mile = 5,280 feet
3 miles = 5280 x 3 = 15,840 feet total.
Divide total feet by the circumference of the tire:
15,840 / 7.33 = 2,161 revolutions.

Answer:
1.72r²
Step-by-step explanation:
total Rectangle area = 4r*2r = 8r²
total circles area = 2(π r²) = 2*3.14*r² = 6.28r²
then:
the area of the shaded region:
= 8r² - 6.28r²
= (8-6.28)r²
= 1.72r²
