Answer:
V =πr^3
Step-by-step explanation:
The height of the pyramid is 3 times the radius of the cone. So we can express height of the pyramid as a function of radius of the cone.
Let's take radius of cone = r
So, the height of the pyramid = 3r
Area of the base of the cone = πr^2 = area of the pyramid.
If the base dimensions of the pyramid are l and b, then area of the pyramid, l x b = π r^2.
The volume of the pyramid = 1/3 x l x b x h
We know, l x b =π r^2 and h = 3r.
Thus, volume of pyramid is = 1/3 x π x r^2 x 3 r
= π r^3.
Thank you.
Answer:
D) The value cannot be determined from the information given
Step-by-step explanation:
If 3x−y=12, what is the value of 8x/2y ?
We can progress till:
- 3x-y=12
- y= 3x-12
- 8x/2y= 4x/y= 4x/(3x-12),
we need the value of x to determine the result.
So the answer is the last choice
