Answer 1

Answer :

Here is your answer

diameter of cone = 3.5 cm and height = 3 cm

Volume of 505 cones = 504 * 77/8 = 4851 cu cm

 

 These cones are melted and made into a sphere..

Volume of sphere = 4851 cu cm              

r³ = 1157.625

r = 10.5 cm

Diameter = 21 cm

Total surface area of sphere = 4 * π * r² 

TSA = 4 * 22/7 * 10.5 * 10.5 = 1386 sq cm
