Question

The volume of cone is 1232 cm^3.If the diameter of the base is 14 cm.then find height of the cone, slant height of the cone, curved surface area of the cone.
​

Answer 1

radius of base= diameter/2 =7cm

volume of cone = (πr²h)/3

or, 1232*3 =22/7( 49h)

or, 3696 =22*7h

•°•h= 24cm

actual height( h )= 24cm=perpendicular

radius=7cm =base

slant height = hypotenuse=√( 24²+7²)=25cm

also

CSA=πrl= 22*25=550cm²
