Answer:
Option D is correct
[tex]\pi r^2[/tex]
Step-by-step explanation:
Area of a circle is given by:
[tex]A = \pi r^2[/tex]
where,
A is the area of the circle
r is the radius of the circle
As per the statement:
The wrestling team needs to calculate the area of a round wrestling mat
Since, wrestling mat is in the shape of the circle.
Using the area of circle formula we have;
[tex]\text{Area of a round wrestling mat} = \pi r^2[/tex]
Therefore, the formula should they use is, [tex]\pi r^2[/tex]
