Answer:

Step-by-step explanation:
The formula of a volume of a cube with side length a:

We have a = 6cm. Substitute:



Greater than 90° but less than 180°.
Answer:
22,40,62
Step-by-step explanation:
0+2=2 2+6=8 8+10=18
2 6 10 14 18 22 four in between
so you will add these numbers each time
18+14=22 22+18=40 40+22=62
Answer:
Center is at (0,0)
Step-by-step explanation:
An equation of ellipse in standard form is:

Where center is at point (h,k)
From the equation of
. First, we add 45 both sides:

Convert into the standard form with RHS (Right-Hand Side) equal to 1 by dividing both sides by 45:

Therefore, the center of ellipse is at (0,0) since there are no values of h and k.
