Verified Answer

10 spheres of radius "R" are melted into making right cones ...

Initial volume of 10 Spheres =

Let N be the number of cones which can be made by melting the sphere.
Volume of a cone =

As per question =

Initial curved surface area = 10×4πR² = 40πR² ~ 125.6R²
Curved surface of the cone = πrl where r is radius of the base and l is the slant height of the cone.

Total curved surface area for the Cone =

Change in Curved Surface Area = 1270.05R² - 125.6R² =1144.45R²

Three solid spheres of radius 3 cm, 4 cm and 5 cm are melted and recast into a solid sphere. What will be the percentage decrease in the surface area?

View answer

A solid metal sphere is melted and smaller sphere of equal radii are formed. 10% of the volumeof the sphere is lost in the process. The smaller spheres have a radius, that is l/9ththe largersphere. If 10 litres of paint was needed to paint the larger sphere, how many litresis need topaint all the smaller spheres?

Directions: A spherical ball of radius R is cut into 2 halves. There is a cylindrical rod of height h, which is 8 times its radius r. The two cut hemispheres are attached at the two ends of the rod. The spheres cover half the length while half length remains open. The complete rod is covered with a paper leaving the top and bottom of the rod. Further to cover the portion of the rod not covered by the hemispheres, the same paper is used but this time the covering has a radius R.What is the ratio of the volume of rod not covered by the sphere to the volume of sphere not covered by the rod?

Three solid spheres of radius 3 cm,4 cm and 5 cm are melted and recasted into a solid sphere. What will be the percentage decrease in the surface area? Correct answer is '28%'. Can you explain this answer?

View answer

A solid metal sphere is melted and smaller spheres, all with the same radius, are formed. 20% of the material is lost in this process. The radius of each smaller sphere is 1/8 the radius of the original sphere. If 20 litres of paint was needed to paint the original sphere, then how many litres of paint would be required to paint all the smaller spheres?
