A drum of oil has a height of 4 ft and a radius of 1.2 ft. The oil cost $22 per ft³.
iogann1982 [59]
Volume of a Cylinder (Drum) = πr²h

Substitute the known values, 
v = 3.14 * (1.2)² * 4
v = 18.09 Ft³

Now, price for 1 Ft³ = $22
So, for 18.09 Ft³ would be: 22 * 18.09 = $397.9

In short, Your Answer would be: $397.9

Hope this helps!

Whats the Approximate volume of the cylinder below in cubic centimeters?? Plz help
Sphinxa [80]

Answer:

Volume of a cylinder = 549.5 cm³

Step-by-step explanation:

Volume of a cylinder = πr²h

Where,

π = 3.14

Radius, r = 5 cm

Height, h = 7 cm

Volume of a cylinder = πr²h

= 3.14 * (5 cm)² * 7 cm

= 3.14 * 25 cm² * 7 cm

= 549.5 cm³

Volume of a cylinder = 549.5 cm³

2. add both together, divide by 16 =8.125. Which means 1 of the stick should more than 8, and 1 of the other stick should be less than 8
3. substitute the equation
4.(55 x 7)+(75 x 9) =1060
