Mathematics

OverLord2011 [107]3 years ago
3 0

Answer:

18

Step-by-step explanation:

1. Create the ratio 12:9

The first number in the ratio is where the length of the shadow will go. The second number is where the length of the building will go.

2. Subtract 21 by 12 to find out how much we have to add to 9. (21-12=9)

3. Add 9 to 9. (18)

We now have 21:18.

What is the total volume of pepsi in this pack of 12? Each cylindrical can has a radius of 1.25in and a height of 4.5in
Alecsey [184]
Total Volume of pepsi in this pack of 12 is 244.3308 in³.

Given:
12 Cylindrical can
radius of 1.25 in
height of 4.15 in

Find total volume:

Volume = π r² h  where π = 3.14
V = 3.14 * (1.25in)² * 4.15 in
V = 3.14 * 1.5625 in² * 4.15 in
V = 20.3609 in³

Volume of 20.3609 in³ is only good for one can. There are 12 cans. 

Total Volume = 20.3609 in³ x 12 cans = 244.3308 in³
