A cone has a base area of 420mm and height of 180mm. What is the volume of the cone.
luda_lava [24]

Cone Volume = PI * radius^2 * height / 3, which can br rewritten as

Cone Volume = base area * height / 3

Cone Volume = 420mm * 60

Cone Volume = 25,200 cubic mm

Someone can help me Pleaseee
Morgarella [4.7K]

Answer:

a. Compressed f toward the x-axis, and then translated it left 4 units.

Step-by-step explanation:

General equation for this is:

 y = a√(x - h) + k

  • a is how much it's being compress or stretched
  • h is how much it's shifted in the x-direction
  • k is how much it's being shifted in the y-direction

We're given:

g(x) = 1/2√(x + 4)

g(x) = 1/2√(x - (-4))

My a-value is 1/2, so the original function f(x) is being compressed by 1/2 toward the x-axis.

My h value is -4 so it's being shifted by 4 units. It's shifted to the left because it's negative.

There is not k-value so nothing is shifted in the y-direction.

Ray Of Light [21]

x=12,y=12√3

sin60=y/24

√3/2×24=y

y=12√3

again

24^2=x^2+y^2

576=x²+12×12×3

x²=576-432

x=√144

x=12
