Tires from two different trucks are being compared. Tire A has a diameter of 32 inches and Tire B has a diameter of 28 inches. H
yuradex [85]

Answer:

12.6 inches

Step-by-step explanation:

-The distance covered in one revolution is equivalent to the circumference oif a tire.

#We calculate the Circumference of A:

C_a=\pi D\\\\=\pi \times 32\\\\=100.5310\ inches

#We then calculate the circumference of B:

C_b=\pi D\\\\=\pi \times 28\\\\=87.9646\ inches

-A has a larger circumference than B and the difference is :

\bigtriangleup=C_a-C_b\\\\=100.5310-87.9646\\\\=12.5664\approx12.6\ inches

Hence, Tire A covers 12.6 inches more than B after one revolution.
