Answer:

37.68 ft^3

Step-by-step explanation:

The parameters used in describing a cone is radius and height

Hence

Radius= 3ft

Height = 2 ft

The volume of a cone is given as

v=\frac{1}{3} \pi r^2 h

substitute

v=\frac{1}{3}*3.14*3^2*2^2\\\\v=\frac{1}{3}*3.14*9*4\\\\v=\frac{1}{3}*113.04\\\\v=37.68 ft^3

Hence the volume is 37.68 ft^3

HACTEHA [7]

Answer:

C=20+0.20N

Fixed monthly fee = $20

Amount charged per minute for long distance calls = $0.20

C denotes total cost such that N minutes are used for long distance calls.

Amount charged for N minutes for long distance calls =0.20N

Therefore, an equation for the total cost, C, when N minutes are used for long distance calls is C=20+0.20N

One printing press can print the whole school newspaper in 12 hours, while another press can print in 18 hours. How long will th
rusak2 [61]

Answer:

7 Hours 12 Minutes

Step-by-step explanation:

So they one of the printer increases at a rate of 1/12 and the other increases at a rate of 1/18. Since you don't know the time it actually takes, you will replace both numerators with and x. (x/12 and x/18). You want to set these up so that they are adding. (x/12 + x/18=1). Since you're adding, you want to change it to the same denominator. The lowest is 36 so you multiply x/12 by 3/3 (so you don't unbalance the equation) and x/18 by 2/2. You'll end up with 3x/36 + 2x/36= 1 which will simplify to 5x/36=1. Multiply each side by 36 to leave the variable by itself. It becomes 5x=36 and when you divide it by 5 you get 7.2. So it's seven and .2 hours, which is equivalent to7 and 1/5 of an hour or 7 hours and 12 minutes.
