Question

find volume, the curved surface area and total surface area of a cone given that perimeter of base = 88cm and height =48 cm​

Answer 1

Answer:

Given , The height of cylinder =14cm

and , the curved surface area of cylinder =88cm

2

we know that ,

the curved surface area of cylinder =2πrh

and 2r=d

here , r=radius of cylinder , d=diameter of cylinder and h=height of cylinder

so , the curved surface area of cylinder =πdh =88cm

2

π×d×14=88

22

×d×14=88

d=2cm

so, the diameter of the cylinder is 2cm.
