Answer:

C) 314 feet.

Step-by-step explanation:

We have been given that a circular track is 100 feet across. We are asked to find the distance around the track.

The distance around the track would be equal to circumference of circle.

\text{Circumference of circle}=2\pi r, where r represents radius of circle.

Since we have been given across distance, so it will be diameter of track.

To find radius we will divide across distance by 2.

r=\frac{100\text{ ft}}{2}=50\text{ ft}

Upon substituting our given values in circumference formula, we will get:

\text{Circumference of circle}=2\times 3.14\times 50\text{ ft}

\text{Circumference of circle}=100\times 3.14\text{ ft}

\text{Circumference of circle}=314\text{ ft}

Therefore, the distance around the track is 314 feet and option C is the correct choice.

What is the difference in the surface area of two cubes, one with edge 15 and one with an edge of 12
Lilit [14]

Remark

A cube has six sides, all of them equal. The formula for 1 side is s^2. The formula for all six = 6s^2.


Step One

Find the surface area of the larger cube.

Area = 6 *s^2

s = 15

Area = 6 *15^2

Area = 6 * 225

Area = 1350


Step Two

Find the area of the smaller cube

Area = 6s^2

Area = 6 * 12^2

Area = 6 * 144

Area = 864


Step Three

Find the difference

Area1 - Area2 = difference

1350 - 864 = 486

The difference is area = 486 units^2 <<<<< Answer


There is a slightly shorter way. Take out the common factor of 6

Difference = 6 * (15^2 - 12^2)

Difference = 6 * (225 - 144)

Difference = 6 * (81)

Difference = 486

What is the domain of the square root function graphed below?
erma4kov [3.2K]

Answer:

The domain of the graph must be x\ge \:-4.

Therefore,

x\ge \:-4\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:-4\:\\ \:\mathrm{Interval\:Notation:}&\:[-4,\:\infty \:)\end{bmatrix}

Hence, option a is true.

Step-by-step explanation:

From the graph, it is clear that the graph is heading towards positive infinity from x=-4.

The point x=-4 is included in the graph as the starting point of the graph i.e. x=4 is showing a closed circle on x=4, and heading towards positive infinity onward.

i.e. [-4, ∞)

Hence, the domain of the graph must be x\ge \:-4.

Therefore,

x\ge \:-4\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:-4\:\\ \:\mathrm{Interval\:Notation:}&\:[-4,\:\infty \:)\end{bmatrix}

Hence, option a is true.
