Question

7. The volume of a cylinder is 300 m then the volume of a cone having the same
radius and height as that of the cylinder is :
A 900 m m
B. 600 m
C.
150 m
D. 100 m​

Answer 1

Answer-:D)100m³

Solution:(above in the image)

Answer 2

Given : The volume of a cylinder is 300 m³

To Find : the volume of a cone having the same radius and height as that of the cylinder  

Solution:

Volume of cylinder = πr²h

r = radius

h = height

Volume of cone = (1/3)πr²h

r = radius

h = height

radius and height of cone and cylinder are given same

Hence : Volume of cone  = (1/3) Volume of cylinder

Volume of cylinder =  300 m³

=> Volume of cone  = (1/3) 300  m³

=> Volume of cone  = 100  m³
