Two metallic right circular cones having their height 4.1 cm and 4.3 cm and the radii of their bases 2.1 cm each, have been melted together and recast into a sphere.
What would be the diameter of the resultant sphere?
A sphere of radius 3 m is melted to form a cylinder and a cone of equal weights and heights. Find the ratio of radii of cylinder and cone.
If in each square, the blue and red areas are equal then find out the ratio of radius between big and small circle?
