It can be noted that the volume of the ball which is a sphere will be 5572.45 cm³.

From the information given, the soccer ball has a radius of 11 cm. This will be calculated by using the volume of a sphere.

Volume = 4/3πr³

= 4/3 × 3.14 × 11³

= 5572.45 cm³

In conclusion, the correct option is 5572.45 cm³.

Answer:

960

Step-by-step explanation:

I used a calculator but its 3% of $8,000 (which I'm pretty sure is 8,000 divided by 3) x 4 so in that's 240x4 which equals 960. Hope this helps have a good day!

Answer:

$960

Step-by-step explanation:

Simple interest is interest that goes up the same amount each period. The formula for simple is A=P(1+rt), where is A is the total amount, P is the principal (aka initial amount), r is the rate (in decimal form), and t is the time.

So, to solve we can use the equation, A=8000(1+0.03*4). In this equation A=8960, meaning that in 4 years the total amount owed, including the initial loan, will be $8960. Since the difference between the principal and the total amount is 960, $960 is the amount paid in interest.

Answer:

At 6 hours the cost is the same. At 10 hours of service Henry is cheaper.

Step-by-step explanation:

This is simple. Follow my lead!

First we must create an equation for George

He charges $90 initially and then $40 per hour

So George's equation is:

[tex]y = 40x + 90[/tex]

Now let's find Henry's equation!

He charges $120 initially and then $35 per hour

So Henry's equation is:

[tex]y = 35x + 120[/tex]

1) To find when they will be the same, just set them equal to each other and solve for x.

[tex]40x + 90 = 35x + 120 \\ - 35x \\ 5x + 90 = 120 \\ - 90 \\ 5x = 30 \\ \div 5 \\ x = 6[/tex]

This means that when x = 6 or at 6 hours in the cost is the same!

2) Just solve both equations with x = 10

[tex]y = 40(10) + 90 \\ y = 400 + 90 \\ y = 490[/tex]

At 10 hours George's service costs $490!

[tex]y = 35(10) + 120 \\ y = 350 + 120 \\ y = 470[/tex]

At 10 hours Henry's service costs $470!

$470 is less than $490 so that means Henry is more cheaper!

Yay! We did it!

Answer:

e = -4

step-by-step explanation:

2e + 3 + 7 = 2

2e + 10 = 2

2e = 2 - 10

2e = -8

e = -8/2

e = -4

verification:

2e + 3 + 7

2(-4) + 3 + 7

-8 + 10

2 ... Therefore proved.

Answer:

e = -4

Step-by-step explanation:

2e + 3 + 7 = 2

2e + 7 = -1

2e = -8

e = -4

First I subtracted the 3 off both sides to keep the equation equal getting me -1. Then i subtracted off the 7 from both sides getting me -8. Finally, i divide both sides by 2 and get -4. E will equal -4.

Answer:

Step-by-step explanation:

If we think about a right triangle, we get that the hypotenuse is 24ft or the length of the ladder. The base of the ladder is 15ft away from the building which is the leg of the right triangle. The screenshot is the diagram (my drawing isn't that good lol:))

Thus we can use cosine function with the angle between the ladder and the ground since we need to find the angle and we get

[tex]cos\alpha = \frac{15}{24}[/tex]

and [tex]\alpha = 51.3 degrees[/tex]

Answer:

22π cm³

Step-by-step explanation:

Let's start with the formulas for volume:

volume of cylinder = πr²h

volume of cone = (1/3)πr²h

Notice the formulas above for the volume of a cylinder and the volume of a cone. The only difference is that the volume of the cone has the fraction 1/3 multiplying the rest, and the rest is exactly the same as in the volume of the cylinder.

That means that if a cylinder and a cone have the same radius and height, the volume of the cone is 1/3 the volume of the cylinder.

Here, the cylinder and cone do have the same radius and height. That means the volume of the cone is 1/3 the volume of the cylinder.

The volume of the cylinder is 66π cm³.

The volume of the cone is 1/3 of that volume, so divide 66π cm³ by 3 to find it.

volume of cone = 66π cm³ / 3 = 22π cm³

Answer: 22π cm³

Answer:

19.25 inches

Step-by-step explanation:

x^2 + 5^2 = 8^2= 64

25+ x^2 = 64

x^2 = 64-25= 39

x = 6.24

perimeter = 19.24

[tex] \\ [/tex]

So to find perimeter of triangle first we have to find value of x.

[tex] \\ [/tex]

As it's Given one angle is 90°

So we can find value of x by using this formula:-

[tex] \\ [/tex]

Hypotenuse ² = Base² + perpendicular ²

[tex] \\ [/tex]

Where :-

Hypotenuse is AC

Base is BC

Perpendicular is AB

[tex] \\ [/tex]

So:-

[tex] \\ [/tex]

⇢AC² = BC² + AB²

[tex] \\ [/tex]

⇢8² = 5² + x²

[tex] \\ [/tex]

⇢64 = 5² + x²

[tex] \\ [/tex]

⇢64 = 25 + x²

[tex] \\ [/tex]

⇢25 + x² = 64

[tex] \\ [/tex]

⇢x² = 64 - 25

[tex] \\ [/tex]

⇢x² = 39 in.

[tex] \\ [/tex]

⇢x = √(39)

[tex] \\ [/tex]

⇢x = 6.2

[tex] \\ [/tex]

Now Let's find perimeter of triangle.

We know :-

Perimeter of triangle = Side one + side two + side 3

So:-

[tex] \\ [/tex]

⇢Perimeter of triangle = AB + BC + AC

[tex] \\ [/tex]

⇢Perimeter of triangle = 5 + 8 + 6.2

⇢Perimeter of triangle = 13 + 6.2
