Answer:
678.24mm³
Step-by-step explanation:
The volume of the cone is computed using the formula:

Where:
r = radius of the circular base
h = height of the cone
π = 3.14
We are given the following:
r = 6mm
h=18mm
π = 3.14
So now that we have that, we just fill in the formula:

Answer:
10 edges
6 faces
6 vertices
10 bases
Step-by-step explanation:
i’m kinda unsure for the bases but the rest are correct :/
Use the distributive property: a (b + c) = ab + ac
(3x² + 2x - 5) (2x - 3) = 3x² (2x - 3) + 2x (2x - 3) - 5 (2x - 3)
... = (6x³ - 9x²) + (4x² - 6x) + (-10x + 15)
... = 6x³ - 5x² - 16x + 15
It is a 45-45 - 90 triangle (as the right angle is split in half for the outer one)
In this case, x is in the hypotenuse. The side lengths follow the 1, 1, √2 formula.
If 1 = 3, then:
3 x √2 = Answer
Answer = 3√2
hope this helps
