Question

a solid cylinder of radius R and a height h is placed over other cylinder of same height and radius find the total surface area of the shape formed

Answer 1

Answer:

4πRH

Step-by-step explanation:

radius of the cylinder = R

height of the cylinder = H

when the cylinder is placed over the cylinder of same height and radius then,

new radius of the cylinder=R

new height of the cylinder = 2H

so, TSA OF THE NEW SHAPE OR CYLINDER IS = 2XπXRX2H

                                                                                 = 4πRH
