Volume of bucket = [1/3*Pi*(2R)^2*2h] - (1/3*Pi*R^2 h)
where R and 2R are bottom and top radii and height 1 meter.
7/3 Pi R^2 h
= 0.66 m^3
= 660 litre
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?
4 solid spheres of radius 1 m, 2 solid cylinders of radius 4 m, height 2 meter and 1 solid cone of radius 2 m, height 4 m are melted to form a bigger solid sphere. What is the radius of this bigger solid sphere in meters?
