The given figure is a combined solid made up of a cylinder and a

cone. The diameter of the base of the solid object is 6cm, length

of the cylindrical part is 116 cm and the total length of the solid

object is 120cm. Find the total surface area of the solid object.

Answer:

Step-by-step explanation:

We have radius of cylinder and radius of cone both are same i.e 3 cm.height of cylinder is 116cm then height of cone will be 4cm then slant height of cone is 5cm. Then total surface area of solid will be the sum of curved surface area of cone &curved surface area of cylinder& also the area of circular base.i.e Πrl+2Πrh+Πr² after calculating

we get 2251.58 cm²
