First find the area of the base, and multiply that by the height. That's the answer.

Area of the base: pi * 3*3 = 3.14*9 = 28.26
Volume of the cylinder: 28.26*8 = 226.08 cubic units

denis-greek [22]

Answer:

There are a total of possible 1820 results.

Step-by-step explanation:

Since there are two competitions, one for boys and one for girls, and we want all the possible results we will calculate the possible combinations for the boys and multiply them by the possible combinations for the girls. This is shown below:

Boys = \frac{15!}{3!(15 - 3)!} = \frac{15!}{3!12!} = \frac{15*14*13*12!}{3!12!}\\Boys = \frac{15*14*13}{3*2*1}\\Boys = \frac{15*14*13}{3*2*1}\\Boys = 455

Girls = \frac{4!}{3!*(4 - 3)!}\\Girls = \frac{4*3!}{3!}\\Girls = 4

Total number of possible results:

results = 4*455\\results = 1820

A delivery truck is transporting boxes of two sizes large and small. The combined weight of a large box and a small box is 80 po
Liula [17]

Answer:

small=15 large=40

Step-by-step explanation:

x=large box

y=small box

55 = x + y

 

50x + 55y = 2825

 

50x + 55( 55 - x) = 2825

 

50x + 3025 - 55x = 2825

 

0 = 55x - 50 x + 2825 - 3025

 

0 = 5x - 200

 

200 = 5x

 

x=40

 

y = 15
