A solid S is made up of a cylindrical part and conical part. The height of the Soild is 4.5m. The common radius of the cylindrical part and the conical part is 0.9m. The height of the conical part is 1.4m.

Question

a. Calculate the volume,correct to 1 decimal place,of soild S.

Answer 1

I assume you know how to find the volume of a cylinder and a cone.
Clearly, the cylinder's height is 3.1

Now just plug and chug.
