Question

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.

Answer 1

115 .40 in²

Explanation:

Let the outer diameter of the bicycle wheel =D₀

Let the inner diameter of the bicycle wheel = D₁

D₀ = 26 inches, while D₁ = 23 inches

Area 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
