Question

A wet bicycle tire leaves a trace of water on the floor. The tire has a radius of 30 cm. and the bicycle wheel makes 3 full rotations before stopping. How long is the trace of water left on the floor?

Answer 1

Answer: 565.714. Please mark as brainliest

Step-by-step explanation:

Circumference of tire = 2£r

= 2×22/7×30

= 1320/7 cm

Now, the tire had took 3 complete rotation = 1320×3/7

= 565.714 cm

Answer 2

565.2 cm trace of water left on the floor

Solution:

Given that,

A wet bicycle tire leaves a trace of water on the floor

The tire has a radius of 30 cm. and the bicycle wheel makes 3 full rotations before stopping

The trace of water left on the floor is the circumference of cycle

The circumference of circle is:

$C = 2 \pi r$

r = 30 cm

Therefore,

$C = 2 \times 3.14 \times 30\\\\C = 188.4$

Given that, bicycle wheel makes 3 full rotations before stopping

trace of water = 3 x 188.4 = 565.2

Thus, 565.2 cm trace of water left on the floor
