Question

A solid metallic cylinder of base radius 3 cm and height 5 cm is melted to form cones, each of height 1 cm and base radius 1 mm. the number of cones is:

Answer 1

HOPE IT HELPS YOU!!!!!!!......

Answer 2

Radius of cylinder=3cm.

Height=5cm

radius of cone= 1mm=0.1cm

height=1 cm

Volume of cylinder =Number of cones×Volume of cone

$Π {R}^{2} h=n \times \frac{1}{3} Π {r}^{2} h$

$Π {3}^{2} \times 5=n \times \frac{1}{3} Π \times 0. {1}^{2} \times 1$

$45=n \times \frac{1}{3} \times (.1 {)}^{2} \times 1$

$45=n \times \frac{1}{3000 }$

n=13500
