Question

the height and area of the base a cone are 9cm an 3186cm cube respectively. find the volume of the cone​

Answer 1

Answer : 9558 cu. cm

Step by step explanation :

Given :

Height of cone : 9 cm

Area of base of cone : 3186 cm^2

To find : Volume of the cone

Solution :

We know that,

Volume of cone = 1/3 π r^2 h

Here,

r is the radius and h is the height.

( height = 9 cm )

Now, Area of base of cone = Area of circle

So , we can say that ,

π r^2 = 3186 sq. cm

Now,

Volume = 1/3 × 3186 × 9

= 3186 × 3

= 9558 cu. cm

Therefore ,

Volume of the cone is 9558 cu. cm

Answer 2

h=9cm

ar of base=3186=πr^2

volume of cone =1/3*πr^2h

=1/3*3186*9

=3186*3

=9558

so, 9558 is the volume of the cone
