Answer:

42.2 cubic inch

Step-by-step explanation:

Applying,

V = πr²h/3.................... Equation 1

Where, r = radius of the circular base, h = height of the cone, π = pie.

But,

r = P/2π..................... Equation 2

Where P = circumference of the circular base.

Substitute equation 2 into equation 1

V = π(P/2π)²(h)/3

V = P²h/12π.................. Equation 3

From the question,

Given: h = 18.4 in, P = 9.3 in

Constant: π = 3.14

Substitute these values into equation 3

V = (9.3²)(18.4)/(12×3.14)

V = 42.2 cubic inch

zheka24 [161]

Answer:

25 minutes

Step-by-step explanation:

Let the amount of time, in minutes, be x.

For Container A, we can write:

200 + 6x [since it has 200 and is being filled with 6 per minute]

For Container B, we can write:

500 - 6x [since it has 500 and is being drained with 6 per minute]

To find, we equate them and solve for x:

$200+6x=500-6x\\6x+6x=500-200\\12x=300\\x=\frac{300}{12}\\x=25$

So, in 25 minutes (m), the two containers will have same amount of water
