How many cylindrical can of bottles 12 cm high and with 6 cm diameter could be filled from a tank containing 125 liters of deter
Orlov [11]

Answer:

368 cans.

Step-by-step explanation:

Volume of 1 can = π r^2 h.

Here h (height) = 12 and r (radius) = 1/2 * 6 = 3 cm.

So V =  π * 3^2 * 12

= 108π cm^3.

The tank hold 125 liters

=  125,000 cm^3, so:

Number of cans that could be filled = 125000/ 108 π

= 368.4.

Three brothers have ages that are consecutive even integers. the product of the first and third boys' ages is 20 more than wice
vladimir1956 [14]
Let the first brother = x 
second brother = x + 2
third brother = x + 4

<span>The product of the first and third boys' ages is 20 more than twice the second boy's age:

x(x+4) = 2(x+2) + 20
x</span>² + 4x = 2x + 4 + 20
x² + 4x - 2x - 24 = 0
x² + 2x - 24 = 0
(x - 4)(x + 6) = 0
x = 4 or -6 (rejected, age cannot be negative)

First brother = 4
Second brother = 4 + 2 = 6
Third brother = 4 + 4 = 8

The three boys are 4, 6, and 8 years old.
