Answer:
V = 549.5 ft³
Step-by-step explanation:
The formula for the volume, V, of a cylinder of radius r and length h is
V = πr²h.
Substituting 2.5 ft for r and 28 ft for h, we get the volume
V = 3.14(2.5 ft)²(28 ft), or 
V = 549.5 ft³
 
        
                    
             
        
        
        
In terms of diameter (d), the area (A) of a circle is given by the formula
 A = (π/4)d²
You have d=20 yd, so the area of the circle is
 A = (π/4)×(20 yd)² . . . . substitute the given information into the formula
 A = 100π yd² . . . . . . . . do the arithmetic
 A ≈ 314.16 yd²
