from a right circular cylinder of radius 7 cm and height 12 cm , a right cone half the height of the cylinder is removed .the base of the cone is one of the plane faces of the cylinder , their centers being the same . if the radius of base of cone is half the radius of base of cylinder , find the total surface area of the solid left
Dear Student,
we can draw the following figure A based on the statements given in the Question.
Total surface area of solid left= Total surface area of Cylinder - Total surface area of cone.
Total Surface Area of Cylinder=
putting values in the formula we get
Total surface area of the cone
Total surface area of cone
Total surface area of the Solid left
=836-114.9
=721.1 cm
