Answer: 3987.8cm³
Step-by-step explanation:
Volume of a cylinder = πr²h
where
π = 3.14
r = diameter / 2 = 10in/2 = 5inches
h = height = 20in
Volume = πr²h
= 3.14 × 5² × 20
= 3.14 × 25 × 20
= 1570inches³
Since 1 inch = 2.54cm
1570 inch = (1570 × 2.54) = 3987.8cm³
Therefore, the volume of the cylinder is
3987.8cm³ cubic centimeters.

Answer:
the price per pound she paid for the ground turkey = $10.515
the price per pound for the white fish
= $5.915
Step-by-step explanation:
Let x = cost of one pound of ground turkey.
Let y = cost of one pound of white
fish
Mrs.Willy bought 3 1/2 (7/2) pounds of ground turkey and 2 1/2(5/2) pounds of white fish and she paid a total of $51.59. This means
7x/2 + 5y/2= 51.59 - - - - - - -1
the white fish is $4.60 per pound cheaper than the ground turkey. This means
y = x - 4.60
To find the price per pound she paid for the ground turkey and the price per pound for the white fish,
substitute y= x - 4.60 in equation 1
7x/2 + 5y/2= 51.59
3.5x +2.5y = 51.59
3.5x + 2.5(x-4.6) = 51.59
3.5x + 2.5x - 11.5= 51.59
6x = 51.59+11.5= 63.09
x = 63.09/6 = $10.515
Substituting x = 10.515 in equation y = x - 4.60,
y = 10.515-4.60
= $5.915
