I really need help, someone please help me
Hoochie [10]

Answer:

18.84 meters.

Step-by-step explanation:

The formula for a circle is πr^2.

πr^2 = 28.26

3.14 * r^2 = 28.26

r^2 = 9

r = plus or minus 3.

But since this deals with the area of a circle, there is no way a radius can be negative. So, the radius is 3 meters.

The formula for the circumference is 2πr.

2 * 3.14 * 3 = 6 * 3.14 = 18.84.

So, the circumference of the circle is 18.84 meters.

Hope this helps!

The answer is 5/3, but I don’t know the solution.
VLD [36.1K]

Check the picture below.

let's bear in mind that the segment MN is simply the sum of MQ + QN, and since M and N are midpoints, they cut that respective section into two equal halves.

\bf \begin{cases} PQ=5QR\\ MN = \frac{PQ}{2}+\frac{QR}{2} \end{cases}\qquad \qquad \cfrac{PQ}{MN}\implies \cfrac{5QR}{\frac{PQ}{2}+\frac{QR}{2}}\implies \cfrac{5QR}{\frac{PQ+QR}{2}} \\\\\\ \cfrac{\frac{5QR}{1}}{\frac{PQ+QR}{2}}\implies \cfrac{5QR}{1}\cdot \cfrac{2}{PQ+QR}\implies \cfrac{10QR}{\underline{PQ}+QR}\implies \cfrac{10QR}{\underline{5QR}+QR}

\bf \cfrac{~~\begin{matrix} 10QR \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~}{~~\begin{matrix} 6QR \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~}\implies \cfrac{5}{3}
