Answer:

200.96 ft²

Step-by-step explanation:

Step 1: <u>Define/formula</u>

To find the area of a circle, multiply the radius by itself twice, then multiply the product by pi.

a=\pi r^2(3.14*radius*radius)

Step 2: <u>Solve</u>

According to the word problem, the radius is 8.

From here, we plug the numbers into the formula.

\pi 8^2(3.14*8*8)=200.96ft^2.

Step 3: <u>Conclude</u>

Therefore, the area of this circle is 200.96 ft.²

jeka94

We have been given that Jenna saves $3 for every $13 dollars she earns. Vanessa saves $6 for every $16 she earns.

We can compare the ratios of saved money to earned money by Jenna and Vanessa as:

\frac{3}{13} =\frac{6}{16}    

Let us simplify our equation.

0.2307692307692308=0.375    

We can see that 0.231\neq 0.375 , therefore, Jenna's ratio of money saved to money earned is not equivalent to Vanessa's ratio of money saved to money earned.
