Question

Write the formula of total surface area of one side open cylinder whose base radius is r &height is h meter

Answer 1

Answer:

Step-by-step explanation:

2×22/7×r×h + 22/7×r square

Answer 2

Given :

An open cylinder with one side opened of height h & radius r

To Find :

Total surface area of given cylinder

Solution :

•Given cylinder can be considered as a open cylinder & circular Base

•Area of open cylinder i.e. Curved surface area of cylinder will be 2πrh

•Curved surface area = 2πrh

•Area of open cylinder is 2πrh

•Area of base i.e. circle of radius r will be πr²

•Area of circular base = πr²

•Area of given cylinder will be sum of area of open cylinder + area of base

•Area of given cylinder = 2πrh + πr²

Area of given cylinder = πr(2h + r) units

•Area of Given cylinder will be

πr(2h + r) units
