You have to know the formula for the volume of a cone.
In high school, there's no other way.

Volume of a cone = (1 / 3) π (radius)² (height)

Volume = (1 / 3) π (12 inches)² (15 inches)

Volume = 720 π = 2,261.95 cubic inches

Rounded to the nearest cubic inch, that's 2,262 cubic inches.

$V \beta = \frac{1}{3} \pi r^{2}h \\ V \beta = \frac{1}{3} \pi 12^{2} * 15 \\ V \beta = 2160 * \frac{1}{3} \pi \\ V \beta = 720 \pi$

Answer:

Step-by-step explanation:

A(x, y)

reflected across the x-axis: A'(x, -y)

reflected across the y-axis: A''(-x, y)

We have A(1, 4)

reflected across the x-axis: (1, -4)

and then reflected across the y-axis: A'(-1, -4)

Expand the following: 6(x – 4y)

Lemur [1.5K]

Answer:

6(x-4y) = 6x - 24y

Step-by-step explanation:

Here, we want to expand the given expression

We can do this using the distributive approach

We have this as;

(6 * x) - (6 * 4y)

= 6x - 24y
