Question

The wrestling team needs to calculate the area of a round wrestling mat. Which formula should they use? A) L x W B) L x W x H C) 2πr D) πr2

Answer 1

Answer: D

Explanation: To find the area of a square you square the radius and multiply it by pi or 3.14

Answer 2

Option D is correct

`\pi r^2`

Explanation:

Area of a circle is given by:

`A = \pi r^2`

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;

`\text{Area of a round wrestling mat} = \pi r^2`

Therefore, the formula should they use is,
`\pi r^2`
