Q:
# The outer diameter of a bicycle wheel measures 26 inches long. The inner diameter measures 23 inches long. What is the area of the tire around the wheel? Use 3.14 for pie.

Accepted Solution

A:

Answer:115 .40 in²Step-by-step explanation:Let the outer diameter of the bicycle wheel =D₀Let the inner diameter of the bicycle wheel = D₁D₀ = 26 inches, while D₁ = 23 inchesArea of tire around the wheel is equivalent to the difference between the area of the outer and inner diameters:Area of tire = π x (D₀² - D₁²)/4---------------------------------------------------(1) = 3.14 x (26²-23²)/4 = 3.14 x 147/4 = 115.395 ≈ 115 .40 in²
