Answer:
Hello! Your answer is D: 75.
Step-by-step explanation:
First we need to find the volume of pyramid A in order to solve this problem:
The formula for the pyramid is: V=
(B)(h)
Now we plug in the numbers:
V=
(81)(4)
V=
(324)
V=108in³
Now we divide pyramid B's volume by pyramid A's:
8,100/108 = 75
So the volume pyramid B is 75 times bigger than the volume of pyramid A!
Hope this helps!
Here, we have: A(r) = 4πr²
We need to calculate it for r = 6,
A(6) = 4π(6)²
A(6) = 4π(36)
A(6) = 144π
In short, Your Answer would be Option D
Hope this helps!
