Answer: Loss of 3 yards
Step-by-step explanation:
The overall gain or loss of all 5 plays will be gotten by adding all the results of the plays given and this will be:
= 7 + 2 - 5 - 23 + 16
Collect like terms
= 7+2+16-5-23
= 25 - 28
= -3
The overall loss of all 5 plays will be -3 yards or loss of 3 yards

Answer:
<h2>r = 15 in</h2>
Step-by-step explanation:
The formula of a volume of a cylinder:
![V=\pi r^2H](https://tex.z-dn.net/?f=V%3D%5Cpi%20r%5E2H)
r - radius
H - height
We have
![V=225\pi in^3\\\\H=1\ in](https://tex.z-dn.net/?f=V%3D225%5Cpi%20in%5E3%5C%5C%5C%5CH%3D1%5C%20in)
Substitute:
<em>divide both sides by π</em>
![225=r^2\to r=\sqrt{225}\\\\r=15\ in](https://tex.z-dn.net/?f=225%3Dr%5E2%5Cto%20r%3D%5Csqrt%7B225%7D%5C%5C%5C%5Cr%3D15%5C%20in)
