Question

if the radius of a one metre long metallic rod in cylindrical shape is 3.5 CM then how many cones of a radius 1 cm and height 2.1 CM can be formed by melting down the rod​

Answer 1

Answer:

volume of rod = π (3.5)^2 ×100

Let n be the number of cone formed

volume of one such cone = (1/3)π×(1)^2×2.1

n × (1/3)π ×2.1= π(3.5)^2 ×100

n = 175
