Answer:
The distance around a circular track if it is 100 feet across is 314 feet.
Step-by-step explanation:
Circumference of circle is given by:
\(C = \pi D\) ....[1]
where
C is the circumference of a circle.
D is the diameter of a circle.
As per the statement:
A circular track if it is 100 feet across.
⇒ \(D = 100 ft\)
then
substitute this value in [1] we have;
\(C = 3.14 \cdot 100\)
Simplify:
\(C = 314\) feet
Therefore, the distance around a circular track if it is 100 feet across is 314 feet.
