So, the line created from the center of the circle to the edge of the circle creates the radius. If it were a straight line from one end of the circle, through the center, to the other end, that would create the diameter. 

So, the answer is radius

<h2>Answer:</h2>

            AB represent the RADIUS of the circular pizza.

<h2>Step-by-step explanation:</h2>

<u>Radius of a circle--</u>

The radius of a circle is a length of a line segment drawn joining the center of a circle to any point on the circumference of a circle.

Here we are given that:

The pizza is in the shape of the circle.

Such that the center is labeled as Point A and there is a point on the circumference of the circle labeled as Point B.

                    Hence, AB denote the Radius of the circular pizza.

The radius of a cone is decreasing at a constant rate of 7 inches per second, and the volume is decreasing at a rate of 948 cubi
nadezda [96]

Answer:

Step-by-step explanation:

We have volume of cone as

V=\frac{1}{3} \pi r^2 h

and for a cone always r/h = constant

Given that r' = rate of change of radius = -7 inches/sec

(Negative sign because decresing)

V' =- 948 in^3/sec

Radius = 99 inches and volume = 525 inches

Height at this instant = \frac{525}{\frac{1}{3} \pi (99)^2} \\=\frac{0.1607}{\pi}

Let us differentiate the volume equation with respect to t using product rule

V=\frac{1}{3} \pi r^2 h\\V' = \frac{1}{3} \pi[2rhr'+r^2 h']\\-948 = \frac{1}{3} \pi[2(99)(-7)(\frac{0.1607}{\pi})+99^2 h']\\

-948 = \frac{1}{3} \pi[2(99)(-7)(\frac{0.1607}{\pi})+99^2 h']\\-948 = 33(3.14)(-2.25/3.14  + 99 h')\\-9.149=-0.72+99h'\\-8.429 = 99h'\\h' = 0.08514

Rate of change of height = 0.08514 in/sec

Vera is using her phone.Its battery life is down to 2/5,and it drains another 1/9 every other. How many hours will her battery l
Margarita [4]

Let x be total hours of battery life. We have been given that battery life of Vera's phone is down to 2/5. So remaining battery life,

1-\frac{2}{5}=\frac{5-2}{5}=\frac{3}{5}

We have been also given that it drains another 1/9 every other hour. Now let us substitute our given information into an equation.

\frac{1}{9}\cdot x=\frac{3}{5}

Now we will solve for x.

x=\frac{3\cdot 9}{5}=\frac{27}{5}

x=(5+\frac{2}{5})hours

Let us convert 2/5 into minutes. We know 1 hour has 60 minutes.

60\cdot \frac{2}{5}=24\text{minutes}

Therefore, remaining battery life will be 5 hours and 24 minutes.
