Question

2. Identify each measurement as the diameter, radius, or circumference of the circular

object. Then, estimate the other two measurements for the circle.
a. The length of the minute hand on a clock is 5 in.

Answer 1

Diameter: 10 in

Radius: 5 in

Circumference of the circular: 31.4 in

Explanation:

The minute hand represents the radius of the clock, therefore the radius is 5 inches. The diameter is twice the radius, so they would equal 10 inches.

And we calculate the circumference like this:

`\begin{gathered} c=2\cdot\pi\cdot r \\ c=2\cdot3.14\cdot5 \\ c=31.4\text{ in} \end{gathered}`
