Volume of a Cylinder Formula: 
- V is volume
- r is radius
- h is height
Step-by-step explanation:
<u>Step 1: Define</u>
Radius <em>r</em> = 2 ft
Height <em>h</em> = 7 ft
<u>Step 2: Solve for V</u>

Answer: 8n
Step-by-step explanation: 5n + 3n
You can round 976 to 1000 and 522 to 500. So it would be
1000 - 500 = 500. The answer you would get after subtracting 976-522 would be more than 400 if you round it.
X=11ft
25-6=14
So ur answer is actually 3
