Question

the curved surface area of a right circular cone of slant height 14cm is 88cm².find the diameter of the base of the cone​

Answer 1

Answer:

2 cm

Step-by-step explanation:

Given ,  The height of cylinder =14cm 

and , the curved surface area of cylinder =88cm2

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 =88cm2

  π×d×14=88

 722×d×14=88

d=2cm

 so, the diameter of the cylinder is 2cm.
