A wet bicycle tire leaves a trace of water on the floor. The tire has a radius of 30 \text{ cm}30 cm30, start text, space, c, m, end text, and the bicycle wheel makes 333 full rotations before stopping. How long is the trace of water left on the floor? Round your answer to the nearest \text{cm}cmstart text, c, m, end text.

Answer 1

565 cm

Explanation:

Given that:

Radius of tire (r) = 30 cm

Number of complete rotations made = 3

To start with :

Obtain the Circumference : 2πr

Hence,

Circumference = 2 * π * r

= 2 * π * 30 = 6

= 188.49555 cm²

Length of trace of water left :

188.49555 * 3

565.48667

= 565cm (nearest cm)
