We know that

[volume of a cone]=(1/3)*pi*r²*h

for r=2/2---> 1 in

h=5 in

[volume of a cone]=(1/3)*pi*1²*5-----> 5.23 in³

**the answer is**

**5.23 in.3**

[volume of a cone]=(1/3)*pi*r²*h

for r=2/2---> 1 in

h=5 in

[volume of a cone]=(1/3)*pi*1²*5-----> 5.23 in³

To find the volume of the cone, you will use the formula for the volume of a cone and replace the r(radius and the h(height) with the given values.

V = 1/3 x pi x r^2 x h

1/3 x 3.14 x 1^2 x 5

V = 5.2281

The volume is approximately 5.23 cubic inches.

V = 1/3 x pi x r^2 x h

1/3 x 3.14 x 1^2 x 5

V = 5.2281

The volume is approximately 5.23 cubic inches.

Question

How many lines of symmetry does a regular polygon with 16 sides have

Solution 1

A** regular polygon** with 16 **sides **has a **line **of **symmetry**. It has 16 **lines **of **symmetry **as well.

**Apothem **for a **regular polygon** is a **line segment **that originates from the **center **of the **regular polygon** and touches the **mid **of one of the sides of the **regular polygon**.

It is **perpendicular **to the **regular polygon's **side it touches.

**Regular polygons** have all **sides **the same and that **apothem **bisects the **side **in two parts, (provable by **symmetry**).

A** regular polygon** with 16 **sides **has a **line **of **symmetry**.

It has 16 **lines **of **symmetry **as well.

16 lines of symmetry is what i got.

Question

Arrange these numbers from least to greatest: 2/5 5/7 4/9
A. 2/5 5/7 4/9
B.2/5 4/9 5/7
C.5/7 4/9 2/5
D.4/9 2/5 5/7

Solution 1

It's B cuz you can divide each fraction for instance 2/5 divide 2 ➗ 5 it equals 0.4 but I turned it into 40% and that's how I found least to greatest

Question

-104=8x what is x ????

Solution 1

The final result is,

Solution 2

-104 = 8x. The x is being multiplied by 8, so to undo the multiplication divide both sides of the equal sign by 8. 8x/8 = x and -104/8 = -13 so x = -13.

Question

Which measure is equivalent to 2.5 liters? A)2.5 mL B)250 mL C) 2500 mL D)25,000 mL

Solution 1

we know that

we are given 2.5L

so, to find 2.5L into mL, we will have to multiply both sides by 2.5

now, we can simplify it

**so, option-C.............Answer**

Question

About 3/4 of the 900 students at Cami’s school went to a dance. Which estimate is the most reasonable for the number of students who went to the dance?

Question

A number cube is rolled 360 times , and the results are recorded as follows : 96 ones , 31 twos , 49 threes , 76 fours , 45 fives , and 63 sixes . What is the experimental probability of rolling a 2 or a 3 ? 1. 0.16
2. 0.22
3. 0.37
4. 0.78

Solution 1

Total number of times rolled = 360

Total number of 2s and 3s = 31 + 49 = 80

P(2 or 3) = 80/360 = 2/9 = 0.22 (nearest hundredth)

**Answer: 0.22**

Total number of 2s and 3s = 31 + 49 = 80

P(2 or 3) = 80/360 = 2/9 = 0.22 (nearest hundredth)

Solution 2

nvm i found it

Solution 1

Question

If the endpoints of AB have the coordinates A(9,8) and B(-1,-2), what us the midpoint of AB?

Solution 1

midpoint of AB:

x = (9 - 1)/ 2 = 4

y = (8 - 2)/2 = 3

midpoint of AB = (4 , 3)

x = (9 - 1)/ 2 = 4

y = (8 - 2)/2 = 3

midpoint of AB = (4 , 3)

Solution 2

For this we must use the Midpoint Formula.

We'll find the y coordinate first.

y=5

Now we'll do the same for x.

x=5

Your final answer is m=(5, 5)

We'll find the y coordinate first.

y=5
