I need to find the cubic footage of my washing machine. It's tub height is 14 inches and the radius of the tub is 10 inches. Can someone please help me!

It is pi*r^2*h
=3.14*10*10*14
=4396 cuic inches
=4396/12*12*12 cubic feet
=2.544 cubic feet

If you are going to model it as an exact cylinder(it's not but it'll be close enough) then it is the area of the base times the height. The base is a circle with a 10 in radius. The area of a circle is pi*r^2. You then multiply this by the height, h*pi*r^2=area=14*3.14*10^2= 4396in^3. One cubic in equals .000578 cubic ft. So 4396 in^3 = 2.54 ft^3

The formula for the volume of a right circular cylinder is Pi*r^2*h. So the answer is:
1400Pi cubic inches, minus the little whirly thing in the middle . . .
Edit: I should have converted this to cubic feet:
1400Pi/(12^3) cubic feet.

Volume will be pi *r^2* h
First you need to convert inches into feet by dividing by 12 (I'm going to leave as fractions.)
r = 5/6 ft
h = 7/6 ft
pi* 25/36*7/6
=pi * 175/216
= 2.5453 cubic feet
hope it helps. I used pi = 3.14159 for accuracy

pi*10^2*14 = 4,398.23 cubic inches 4398.23/1728
= 2.55 cubic feet
