Question

The vertical height of a right circular cone is 9cm and radius of its base is 4cm. Find its volume​

Answer 1

Answer:

Given ,

r = 4 cm

h = 9 cm

volume of cone = 1/3 πr²h

v = 1/3 × 4² × 9

  = 3×16

  = 48 cm³

Hence , the volume is 48 cm³

Answer 2

Answer:

Ans 48pi

Step-by-step explanation:

we know

vol. of cone= 1/3pi r^2 h

above this question we have

r =4

and h=9

therefore,

= 1/3× pi × 4 × 4 ×9

= 48pi..
