Riya melts a solid metallic sphere of radius 10.5 cm and casts it into small cones, each of base radius 3.5 cm and height 3 cm. How many complete cones can she make? (use π = 22/7)

Question

Accepted Answer

126. Sphere V = 4/3π*10.5^3 = 4/3π*1157.625. Cone V = 1/3π*3.5^2*3 = 1/3π*36.75 = 12.25 π. n = 4/3*1157.625/12.25 = 1543.5/12.25 = 126 cones.
