Respuesta :

The circumference of the wheel is about 85 inches.

Solution:

Diameter of the wheel = 27 inches

Radius of the wheel = 27 ÷ 2 = 13.5 inches

The value of π = 3.14

Wheel is in the shape of a circle.

Circumference of the circle:

[tex]C=2\pi r[/tex]

[tex]C=2 \times 3.14 \times 13.5[/tex]

C = 84.78

Round to the nearest whole number, we get

C = 85 inches

The circumference of the wheel is about 85 inches.
