Answer:
(d − 3) (d + 3) (d² + 9)
Step-by-step explanation:
d⁴ − 81
Factor using difference of squares.
(d² − 9) (d² + 9)
Factor using difference of squares again.
(d − 3) (d + 3) (d² + 9)
Answer:
The answer is t/3=20
The right diagram is the one that has the orange boxes with 20s and has a t on top
Okay. The equation for a sphere's surface area is A = 4 * pi * r^2. Let's plug 5 in for r.

I got 314 cm^2 is the surface area, but it always helps to double check work! Hope this helps!
For a triangle 30-60-90,
If shorter leg is x, then hypotenuse is 2x.
So, if shorter leg is 4,
then hypotenuse is 2*4 = 8.
Answer is 8.
Answer:
The sharing cone holds about 9 times more popcorn than the skinny cone.
Step-by-step explanation:
The volume of a cone is given by the following formula:

In which r is the radius and h is the height.
Two cones:
Both have the same height.
The sharing-size cone has 3 times the radius of the skinny-size cone.
Skinny:
radius r, height h. So

Sharing size:
radius 3r, height h. So

About how many times more popcorn does the sharing cone hold than the skinny cone?

The sharing cone holds about 9 times more popcorn than the skinny cone.
