A grain silo consists of a cylinder with a hemiphere on top. Find the volume of a silo in which the cylindrical part is 58 feet tall and has a diameter of 19 feet.The volume of the silo is ? cubic feet
You need to solve for the cylinder part and you need to solve for the hemispere part cylinder = area of round base x height 9.5 x 9.5 x Pi x 58 = hemispere = 1/2 sphere volume sphere volume = 4/3 x Pi r cubed you need half of this 2/3 x Pi x r cubed 2/3 x Pi x 9.5 x 9.5 x 9.5 = add the sphere and cylinder volumes together to get the answer
