Answer:
1050 times larger
Step-by-step explanation:
simply multiply two expression and divide the first by the the second
(8×105)/(8×10^-1)= 1050
This problem is a difference of squares. So to solve this you want to factor it out so you get two numbers that multiple to -9 and add to 0. That would be -3 and 3
f(x)=(x-3)(x+3)
So your solution when you set f(x) to 0 would be -3 and 3.
I think it may be a 180 degree angle but I wouldnt trust myself so idk
The volume of oblique cone =
Now radius is doubled is now it is 2r
And height is reduced to 2/3 of its original size that is 2/3 h
So plugging the values we get volume
New Volume = 
= 

It means the volume becomes 4 times
