Find the volume of a cone with base area 9π ft2 and a height equal to twice the radius.

NEED ANSWER QUICK

ft cubed

Step-by-step explanation:

The volume of a cone is: , where is the base and h is the height.

In this case, we see that the base is: . Solving for r, we see that the radius is .

The height is twice the radius, so h = 2 * 3 = 6. Now, we have all the necessary values that we can plug into the equation to get the volume:

Thus, the answer is ft cubed.

Hope this helps!

18π ft³

Step-by-step explanation:

Base area = pi × r² = 9pi

r² = 9

r = 3

h = 3 × 2 = 6

Volume = ⅓ × pi × r² × h

⅓ × 9pi × 6

18pi ft³

g(x) is the negative form of f(x)? because whenever its the negative form it reflects its self over the x axis. idk if this is right though.

step-by-step explanation:

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
