Answer: 8.66

So to Solve this we are going to be using Tangent.

Tangent: opposite/adjacent

Tan60 = y/5

Tan60 * 5 = y/5 *5

Tan60 * 5 = y

8.66 = y

Tan (60) = y/ 5
y = tan(60) * 5
and you know tan(60) = √3
so
y = 5√3

answer
5√3 (exact value)

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,

Annette [7]

Answer:

186 cm

Step-by-step explanation:

Since the bicycle wheel is making a rotation and not a revolution, the bicycle wheel is at one point.

The length of the trace of water left on the floor is simply the circumference of the bicycle wheel

Circumference = 2πR

where R = radius of the bicycle wheel

and π = pie

Circumference = 2 × (22/7) × 30 = 188.57143 cm
