Answers

Answer 1

Answer:

1,570 cubic cm

Step-by-step explanation:

Given,

Radius of the cone = 10 cm

Height of the cone = 15 cm

Therefore, volume of the cone

[tex] = \frac{1}{3} \pi {r}^{2} h[/tex]

[tex] = \frac{1}{3} \times 3.14 \times 10 \times 10 \times 15[/tex]

= 1,570 cubic cm (Ans)

~SHOW ALL OF YOUR WORK~ Find the volume of this figure. Round to the nearest tenth.

Answers

Answer:

Rounded to the Nearest Tenth is V=769.3π

Step-by-step explanation:

The diameter of the figure is 7, so the radius is 3.5. So, the radius is 3.5

The height is 20

Formula for cylinders= V= Bh or  V=πr2h

I will use  V=πr2h

V=π(3.5)²(20)

V=π(12.25)(20)

V=π(245)

V=769.3π

Hope this helped

Answer:

V=769.3π

Step-by-step explanation:

The diameter of the figure is 7, so the radius is 3.5. So, the radius is 3.5

The height is 20

The formula for cylinders is V=πr2h

V=πr2h

V=π(3.5)²(20)

V=π(12.25)(20)

V=π(245)

V=769.3π

Answer:

I believe the answer is 8m.

Step-by-step explanation:

Answer:

Step-by-step explanation:

1) Perimeter = 2m + 3m +3m + 2 + 2m + 2

                =  2m + 3m + 3m + 2m + 2 + 2         {Combine like terms}

                = 10m + 4

2) 10m = 2 * 5 * m

    4    = 2 * 2

GCF = 2

10m + 4 = 2 *5m + 2*2

             = 2*(5m + 2)

Use the given angle measures to answer the following questions.

Part A: If Angle A and Angle B are vertical angles, what is value of x?

A. 8
B. 10
C. 28
D. 35

Answers

Answer:

[tex]\Huge\boxed{A.8}[/tex]

Step-by-step explanation:

Hello There!

If you didn't know vertical angles are congruent

That being said we can use this equation to solve for x

40 = 5x

Objective: Isolate the variable using inverse operations

To get rid of the 5 we divide each side by 5

40 / 5= 8

5x/5=x

we're left with x=8

To check our answer we can plug in 8 to x and if it equal 40 then the answer is correct

5(8) = 40

So the answer would be 8

Answer:

8

Step-by-step explanation:

40÷5=8

Find the slope of the line that passes through (13, 7) and (13, 11).​

Answers

Answer:

there's no slope.

Step-by-step explanation:

m = (11 - 7) ÷ (13-13)

m = 4 ÷ 0

m = undefined, since you cannot divide by 0

Answer:

undefined since they have the same x value

Step-by-step explanation:

if you plot these 2 points on a graph you'll see that they are vertical, I remember that if they are like this then they have an undefined slope, if they have the same y value they will be flat or a slope of 0.

a = 250x + 1300

Step-by-step explanation:

250

$250 is the amount added to savings account every month

Initial amount was:

Answers

Answer:

600

Step-by-step explanation:

so basically all you have to do make the fractions equal. if 6 is equal to 10 then 600 is equal to 1000

600/1,000.

I believe the way you solve this problem is with multiplication.

Every time you multiply something by 10 you simply add a zero. The same goes for 100, you just simply add two zeros.

Since this is a fraction, you do the same for the numerator.

10 times 100 is 1,000 and 6 times 100 is 600. 600/1,000.

If this is incorrect, please, don't refrain to tell me.
