Circumference of the circle as 15 pi inches find the diameter

1 answer:

4 0

The formula for the circumference of the circle is 2πr or πd with r being the radius and d being the diameter. These 2 gives the same result because d=2r

Now because we know that the circumference is 15pi, we just need to reverse to find the diameter.

π*diameter=15*π

We can divide π from both sides.

diameter=15

Hope this helped!

Answer:

Part A: Histogram :)

Part B: Described below! :)

Step-by-step explanation:

Part A:

A histogram is the best choice because it can show the numbers for multiple categories in a quick and easy manner :)

Part B:

The x axis will have the categories of quiz scores! The y axis will show how many students got that score.

We then put the categories from smallest to largest along the x axis. We will also put the numbers that go with the categories above the category!

Done! you have made your histogram!

Have an amazing day!!

If tan theta = startfraction 11 over 60 endfraction, what is the value of cot theta?

Dennis_Churaev [7]

The value of $cot\theta$ when $tan\theta =\frac{11}{60}$ comes to be $\frac{60}{11}$ .

Given that trigonometric ratio:

$tan\theta = \frac{11}{60}$

<h3>What is the tangent of an angle?</h3>

The tangent of an angle is the ratio of the opposite side(to that angle) to the adjacent side(to that angle).

So, for the given problem

Opposite side to $\theta$ = 11

Adjacent side to $\theta$ = 60

So, $cot \theta =\frac{AdjacentSide }{OppositeSide}$

$cot\theta =\frac{60}{11}$

Therefore, the value of $cot\theta$ when $tan\theta =\frac{11}{60}$ comes to be $\frac{60}{11}$ .

trapecia [35]

Answer:

= <em>1</em><em>4</em>

Step-by-step explanation:

So my way of doing it is to simply put 20% in decimal so

20= 0.20

Then multiply that by 70

0.20× 70 = 14%

There are probably other ways to do it but I find this way easier
