Volume of cone if r = 2 cm, h = 4 cm is …………..

In a cone, r=8 cm, h=11 cm then l= ……….. cm.

In a cone, r=7 cm, h=10 cm then l= ……….. cm.

The volume of cone is 462 cm^(3), r=7 cm then h = ……. cm.

If h is the height, I the slant height and r_(1), r_(2) radii of the circular bases of the frustum of a cone, then slant height of the frustum = sqrt(( r_(1) - r_(2))^(2) + h^(2)) . Find the height of the cone of which the frustum is a part = (h r_(1) /( r_(1) - r_(2) ).We have a bucket in the form of frustum of a cone in which h = 8 cm, r_(1) = 9 cm and r_(2) = 3 cm.

The volume of a right circular cone with radius 9 cm and height 14 cm is ……….

Find the volume of a right circular cone if r = 14 cm and h = 9 cm.

Assertion (A) : For a cone, if r=6 cm, h=12 cm and deltar=deltah=0.06 cm, then approximate error in volume is 3.6pi c.c Reason (R ) : cone valume v=pir^(2)h and error approximately, is dv=pi.(2r.deltar).deltah Choose the correct answer
