Before the baseball season begins, a field manager outlines the "on-deck" circle with chalk and covers the area with dirt.



If the "on-deck" circle has a diameter of 6 feet, about how long is the chalk outline?

Answer:

C maybe

Step-by-step explanation:

The field is circular and the line drawn by chalk is length of the rim of the circular field, and is called circumference. It can be calculated from radius(or diameter) of the circle.

The length of the chalk outline is given by:

Option A: 19 feet.

The length of the chalk outline.

[tex]|Circumference| = 2 \times \pi \times r = \pi \times d[/tex]

where r represents the radius of the circle and d represents the diameter of the circle.

The diameter d = 2 times r always. (diameter is twice of length of radius)

Thus, we have:

[tex]\text{Length of chalk line} = \pi \times d = \pi \times 6 \approx 18.84 \approx 19 \rm \: feet[/tex]

The length of the chalk outline is given by:

Option A: 19 feet.
