from the top of a solid cone of height 12 cm and base radius 6 cm, a cone of height 4 cm is removed by a plane parallel to the base. find the total surface area of the remaining solid (use π=3.17)please answer it...

vol of big cone is 1/3*π*12*6...(1/3*π*r*h)
....so answer would be...24π. .lets take it V1
vol of small cone...applying same formulae...
so it would be...1/3*π*4*6...radius is same as the are parallel...so we get...8π...this is V2
V1-V2
24π-8π
79.25-25.36=53.89
