Answer:

In circumference, pi is in the formula to solve circumference. In the formula for area you also need pi but with the square of the radius. The diameter is two times the radius and sometimes you need the diameter to find something of a circle. Pi is in all the formulas of circles including diameter radius and formula of circumference.

Answer:

X= -5

Step-by-step explanation:

do you need steps?

5x +7/2 = 3x/2 -14

10x+7/2 = 3x-28/2

2(10x+7) = 2(3x-28)

20x +14 = 6x - 56

20x -6x = -56 - (14)

14x = -70

x = -70/14

x = -5

The volume of a rectangular prism is represented by the following equation:

V=w*h*l

Where the variables are for volume, width, height, and length, respectively.

We are given that the area of one end is 16 cm² (units have to be correct when solving these problems, so it's 16 cm², not 16 cm as described in the problem). We know that A=w*h

Using this knowledge, we can change the volume equation to our needs.

V=w*h*l

V=(w*h)*l

V=A*l

Note: We know that A is 16 since it's given

V=16*l

The volume is 208 cm³ (once again, incorrect units given). Insert this into the equation.

208=16*l

Divide both sides of the equation by 16.

13=l

The length is 13 cm.

Let me know if you need any clarifications, thanks!
