Answer:

B -2

Step-by-step explanation:

y = kx  where k is the constant of variation

We have -4y = 8x

Divide each side by -4

-4y/-4 = 8x/-4

y = -2x

The constant of variation is -2

Fine the area of a circle that has a diameter of 12 inches A=3.14r2
Alexus [3.1K]

The area of circle is 113.04 in^2

Further explanation:

The area of circle is calculated by using pi and radius.

We are given

Diameter = d = 12 inches

pi = π = 3.14

r = \frac{d}{2} = \frac{12}{2} = 6\ inches

Area = \pi r^2\\= 3.14 * (6)^2\\= 3.14 * 36\\=113.04\ in^2

The area of circle is 113.04 in^2

Keywords: Circle, Area of Circle

What is the height of a rectangular prism that has a volume 192 cubic feet and a base with an area of 48 square feet?
Westkost [7]

Answer:

A rectangular prism has 3 measurements: length (l), width (w), and height (h)

The volume of a rectangular prism has the formula: V=lwh

The area of the base of the rectangular prism is its length times its width; or

Area of base = lw

So, the volume of the rectangular prism can be written as:

Volume = area of the base * height

Substitute in your numbers:

192=48*h

h=192/48

h=4

So the height is 4 feet

Step-by-step explanation: Hope this helps. :))
