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
