How do you find the radius for a sphere?

10 Points shall be awarded for answering!

Answers

Answer 1
Given diameter: r = d / 2,
Given area: r = √[A / (4 * π)],
Given volume: r = ³√[3 * V / (4 * π)],
Given surface to volume ratio: r = 3 / (A/V).


Some equations based on what is given :)
Answer 2
If given the diameter, divide by 2. For example if the diameter is 16, that would mean the radius would be 8. If the problem doesn’t state the diameter, divide the circumference by pi. So if the circumference was 24, that would make the diameter 7.639437268. From there you divide that by 2 to get the radius. Hope this helps!

Answer:

108

Step-by-step explanation:

So, to start, we can calculate the fuel used in March by using the following equation:

(40x240)/100

Which is 96. So the furnace burned 96 gallons of fuel in March and was left with 144 gallons. Now we need to find out how much of its remaining fuel it burned in April, so we use this:

(25x144)/100

Which is 36. So it burned another 36 gallons of fuel in April, leaving it with 108 gallons still in the tank.

Mai distributed another group of flyers equally among the five volunteers. Then she remembered that she needed some flyers to give to teachers, so she took 2 flyers from each volunteer. Then, the volunteers had a total of 40 flyers to hang up. How many flyers did Mai distribute to each of the five volunteers originally? The answer is 10, but how do you figure that out? Please leave an explanation of how you got your answer.

Answers

Step-by-step explanation: So, she took 2 from each of the volunteers, and there were 5 volunteers in total. What I did, was I found out how many people were taken in total and given to the teachers, which was 10 (2*5), and then I added it to the total number of flyers still with the volunteers (40), which equals 50. Divide that by 5 (number of groups) and you get 10.

Answer:

question 5 = 167.5ft^3 so yeah correct

question 6 = the 4th answer = 2388ft^3

Volume  using full pi = ; 2389.2ft^3 or 2389 ft^3 to 4sf.

Step-by-step explanation:

question 6 =

We have 13 Diameter. Which is 6.5 radius

D = 13

R = 6.5

H = 18

Surface area a of cylinder pi x 6.5^2 =  132.73229

or 42.25pi

Then we just multiply by the height to get the volume.

42.25x 18 = 760.18 pi

or 132.73229 x 18 =2389.18122

Volume = 2389.2ft^3 or 2389 ft^3 to 4sf.

As the answer given is 2388ft^3 then show your pi workings as 3.14 or 3.1459

Answers

Answer:

18 liters

Step-by-step explanation:

since 6 kiloliters are equal to 600000 centiliters you would have to divide it by 100. Then you will get 6000 centiliters which you subtract by 4200 centiliters. After that, you get 1800 centiliters which is equal to 18n liters.

Let's plug in the measurements:

2(18+27) =

2(45) =

90

So the parallelogram is 90 now we have the perimeter of the semi cirlce already which is 18

Dennis and Eduardo are studying transformations using triangles. A ABC and A DEF are both plotted on a coordinate plane
Dennis notices that if he reflects A ABC across the y-axis and then translates it down 4 units, the result is A DEF.
Eduardo says that he can first translate A ABC down 4 units and then reflect it across the y-axis in order to get A DEF.
Is Eduardo correct? Explain your answer and tell whether A ABC and A DEF are congruent.
Type your answer in the box below.

Answer:

i think they are

Step-by-step explanation:

The translation of the 4 units right then a reflection across the x-axis will map triangle ABC onto triangle DEF.

What are the translation and reflections of an image?

Translation of an image indicates the horizontal or vertical movement of that image. The reflection of an image indicates the mirror image of the given image along with a fixed-line.

Here, when we translate the triangle ABC to the right by 3 units, then point A will be at (2, 6), point B will be at (2, 3), and point C will be at (4, 3.).

Hence, after reflecting the triangle ABC, we get the triangle DEF.

the total measurement for every triangle is 180 so js add up what they give you and subtract it from 180.

hope this helps

Answer:

Step-by-step explanation:

Sum of all angles of a triangle = 180

1) 60 + 87 + b = 180

          147 + b = 180       {Subtract 140 from both sides}

                   b = 180 - 147

b = 33

2) b + 83 + 30 = 180

          b + 113 = 180    {Subtract 113 from both sides}

                  b = 180 - 113

b = 67

The general equation of a line is y=mx+b.

The equation you currently have is y=5x+b.

Plug in the point (3,3) which will get you 3=5(3)+b.

Solve the equation by solving what the y-intercept (b) is to create the new final equation.

3=5(3)+b

b=3-15
