For this case, we have that by definition, the circumference of a circle is given by:

C = \pi * d

Where:

d: Is the diameter of the circle given by 2r, that is, twice the radius.

If we have a circle with a diameter equal to 8cm, then the circumference is given by:

C = \pi * 8 \ cm

ANswer:

Option C

8 \pi \ cm

Answer:

The correct answer is option 3). 8π cm

Step-by-step explanation:

<u>Formula for circumference of circle</u>

circumference  = 2πr   where r is the radius of circle.

It is given that, Circle with center D and diameter of 8 cm labeled.

<u>To find the circumference</u>

diameter = 8cm

radius = diameter/2 = 8/2 = 4

circumference  = 2πr

circumference  = 2 * π * 4 =  8π

Therefore the circumference of given circle is

The correct answer is option 3). 8π

mr_godi [17]

The distance between the boat and the ocean's floor is 19m

<h3>How to get the distance from the ship to the ocean's floor?</h3>

We can see this as a right triangle, where the rope with the anchor is the hypotenuse. So we already know that the hypotenuse measures 30m.

We also know an angle, it measures 39°, and we want to get the opposite cathetus to said angle (the height).

Then we use the relation:

Sin(a) = (opposite cathetus)/(hypotenuse).

Replacing the values that we know, we get:

Sin(39°) = d/30m

sin(39°)*30m = d = 18.9m ≈ 19m

The distance between the boat and the ocean's floor is 19m.

Function h models an object's height in feet after x seconds have passed. Which equation shows that the object's height increase
ASHA 777 [7]

Answer:

C

Step-by-step explanation:

We know that function <em>h</em> represents an object's height in feet after <em>x</em> seconds.

In that case, option A) h(15) = 100 means that after 15 seconds, the object's height is 100 feet.

Option B) h(100) = 15 means that after 100 seconds, the object's height is 15 meters.

Therefore, neither A nor B are correct.

Option C) h(15) - h(0) = 100 means that between the zeroth and 15th second, their difference is 100 feet.

In other words, the object's height increased by 100 feet over the first 15-second period.

Option C is correct.

For Option D), it gives us the average rate of change. (h(15) - h(0)) / (15) = 100 means that for the first fifteen seconds, the height of the object increased at an average rate of 100 feet per second.
