V=hpir^2

tricky, they didn't give us radius
they just gave circiufmerece

c=2pir
25.12=2pir
divide by 2 both sides
12.56=pir
divide by 3.14 both sides
4=r

What is the volume of this oblique cone? 12π cm³ 40π cm³ 60π cm³ 120π cm³ An oblique cone with radius of six centimeters and hei

Pepsi [2]

We have to find the volume of oblique cone. An oblique cone is a special type of cone in which the apex is not located directly above the center of the circular base, so it looks like a slanted cone.

Volume of oblique cone = $\frac{1}{3} \Pi r^{2}h$

where 'r' is the radius and 'h' is the height.

Here r = 6 cm and h = 10 cm

Volume = $\frac{1}{3} (\Pi (6)^{2} \times 10)$

= $\frac{360\Pi }{3}$

= $120\Pi cm^{3}$

So, the volume of the given oblique cone is $120\Pi cm^{3}$ .

Option 4 is the correct answer.
