Answer:

π = C / d

Step-by-step explanation:

The circumference of a circle is given by the general formula;

C = 2 * π * r .... or C = π d  (r = radius, d = diameter)

We can easily modify the second formula to isolate π in order to express the circumference in relation to the diameter:

π = C / d

To obtain π, you need to divide the circumference by the diameter.

We're used to think about the circumference in terms of radius... but since we deal with 2 * r * π and that 2 * r = d...  it's also convenient to use the diameter.

Which ordered pair could not be the coordinates for a clockwise rotation of the point W(-3, 4)?
Eduardwww [97]

Step-by-step explanation:

<em>Look at the picture.</em>

Any pair of choice can be the coordinates of the rotation of the point

W (-3, 4) clockwise.

All points have the same distance from the beginning.

The formula of a distance between the origin and a point (x, y):

d=\sqrt{x^2+y^2}

W(-3, 4)

d=\sqrt{(-3)^2+4^2}=\sqrt{9+16}=\sqrt{25}=5

(3, -4)

d=\sqrt{3^2+(-4)^2}=\sqrt{9+16}=\sqrt{25}=5

(4, 3)

d=\sqrt{4^2+3^2}=\sqrt{9+16}=\sqrt{25}=5

(-4, -3)

d=\sqrt{(-4)^2+(-3)^2}=\sqrt{9+16}=\sqrt{25}=5

(-4, 3)

d=\sqrt{(-4)^2+3^2}=\sqrt{9+16}=\sqrt{25}=5

A warehouse has three shelves that can hold 8, 12, or 16 skateboards. Each shelf has sections holding the same number of skatebo
Aliun [14]
The greatest number of skateboards that can be stored would be the number that is the highest common factor of 8, 12, and 16

Factors of 8 = 1, 2, 4, 8
Factors of 12 = 1, 2, 3, 4, 6, 12
Factors of 16 = 1, 2, 4, 8, 16

The highest common factor  = 4

Hence, the greatest numbers of skateboard that can be stored in each section is 4

A square had a perimeter of 38 inches. We want to know the length of each side.
MissTica

Answer: 9.5

Step-by-step explanation:

Since a sqaure has all 4 equal sides, you can divide the square by 4 since there are 4 sides and it will be equal.

38 ÷ 4 = 9.5

Therefore, the length of each side will be 9.5. Hope this helps!
