7 0

Answer:

So, 5 x 6 = 30

150 - 30 = 120

Then find out the number of hours by dividing 120 by 18.

In this case,

120 / 18 = 6.666666666666667

The answer is 6.6 or at estimation 7.

Find the volume of soup can if the diameter is 6.5 in and the height is 9 in
Nitella [24]

Answer:

V =298.49625 in^3

Step-by-step explanation:

Volume of a cylinder is given by

V = pi * r^2 *h

We know the diameter so we can find the radius

r = d/2 =6.5/2 = 3.25

and we know the height =9

V = pi * (3.25)^2 *9

V = pi*95.0625

If we approximate by 3.14

V = 3.14*95.0625

V =298.49625 in^3

(12*8)+(12*8)+(10*8)+(10*8)-60=160+192-60=292

There are 3 bedrooms so

292*3=876
