Find the volume of the sphere. Either enter an exact answer in terms of π or use 3.14 for π and round your final answer to the nearest hundredth.

Answers

Answer:

33.49

Step-by-step explanation:

The formula for volume of a sphere is 4/3 × π × radius³

The radius in this case is 2

2³ = 8

4/3 × 8 = 10 2/3

10 2/3 × 3.14 ≈ 33.49

You can also right it as (10 2/3) × π

The radius of a circle is 6.5 inches. Find the circumference of the circle. Use pi as 3.14. Explain your steps.

Answers

Circumference= 2piR
1) Fist do 2 times pie. 2x3.14= 6.28
2) With the remaining answer times it by the radius. 6.28x6.5= 37.994inches

The correct answer is b or 8:2 and 4:1.


To compare ratios, you need to have a common second number. By multiplying each ratio by the second number of the other ratio, you can determine if they are equivalent. Multiply both numbers in the first ratio by the second number of the second ratio.
it’s the second one down 8:2 and 4:1

C= 2 pi

the formula for circumference is 2**r. so plug in the radius and it will be 2**3. that equals 6. I am not sure whether for your problem you’re supposed to multiply it by rounded pi, so the following answer is what you would get if you multiplied by pi, rounded. Now is infinite so we round it to 3.14. then multiply 6 by 3.14 and get 18.84 cm.

In Harold’s class, there are 7 boys for every 6 girls. Identify three equivalent ratios to compare boys to girls.

Answers

Answer: The ratio of 6 /7 represent the number of boys to the number of girls in one classroom. You are given a total number of boys and girls.  

 

So, your ratio has to represent how many boys to the total number of boys and girls in one classroom, or 13.

 

The proportion becomes, 6 / 13 = x / 78.

 

Cross multiply getting, 13 * x = 6 * 78

 

Divide by 13 to solve for x, or x = 36.

 

There are 36 boys in all of the classrooms and 42 girls in all of the classrooms.

 

The ratio of boys to girls in all of the classrooms is 36 / 42, or 6 / 7.

Look at Figure 2. What is the measure of x ? ( Hint: you may need to use triangle ACE to help you;) notice the right angle??? NEED HELP ASAP PLEASE

Answers

Answer:

60°

Step-by-step explanation:

Let angle BAE = angle ACD = x

                                BCD  = AEC = 60°

EAC + FCA + ECF + AEC = EAC + x + 60° + 60° = 180°

                                 EAC = 60° - x

                                 BAC = EAC  + BAE = 60° - x + x = 60°

x=60° because of the reflection, hope this helps :)

Josh ran 14.8 km in the morning. After lunch, he continued running. When he finished the run, he had covered 31.1 km in all. Write an equation that can be used to find how far Josh ran after lunch.

Answers

14.8 + x =31.1
X equals how much he ran after lunch

Answer:

14.8 + x = 31.1

Step-by-step explanation:

This is the best equation to put as the answer.

If you want to solve it, this is how you would solve it.

14.8 + x = 31.1

Make it so that the variable x is by it's self.

14.8 + x - 14.8 = 31.1 - 14.8

x = 31.1 - 14.8

Now solve the subtraction problem.

x = 31.1 - 14.8 = 16.3

So, now you have your answer

x = 16.3

To make sure it's correct, use the addition method.

16.3 + 14.8 = 31.1
