Mathematics

barxatty [35]3 years ago

the following formula is used to find the volume of a cone

V - volume = πr²h/3

where π = 3.14, r - radius and h - height

the height hasnt been directly given

we can find height using Pythogoras theorem for the right angled triangle given

4² + h² = 5²

16 + h² = 25

h² = 25 - 9

h² = 9

h = 3

height = 3

diameter is 4, therefore radius - diameter / 2 = 4/ 2 = 2

radius = 2

substituting values in the volume equation

V = 3.14 x 2² x 3 /3

= 12.56

volume is 12.56 cubic units
