Question

The circle with center C was used as a model for a swimming pool. The length of BC%7D" id="TexFormula1" title="\overline{BC}" alt="\overline{BC}" align="absmiddle" class="latex-formula"> is 10 m. What is the area of the pool?

Answer 1

Answer:

314.16

Step-by-step explanation:

Because we have the radius given to us by BC, we can simply input it into the formula to find the area of a circle, pi(r)^2.

After we insert the given radius, we have pi(10)^2.

We can simply input it into our calculator to find the answer.

Answer 2

Okay okay so when solving for the area you have to use:
A= πr ²
(pi r squared)
A=10x10
A=100π
A ≈314.2
