Answer:
h = 4 cmStep-by-step explanation:
V = π r² h
where r = 3 cm
V = 36π cm³
solve for h
plugin values into the formula:
36π = π 3² h
h = 36π
π 3²
h = 4 cm

A globe has a diameter of 14 inches. Find the volume of the globe. Round your answer to the nearest tenth.
Answer:
1436.8 in³ (nearest tenth)
Step-by-step explanation:
A globe is in the shape of a sphere.
[tex]volume \: of \: sphere = \frac{4}{3} π {r}^{3} [/tex]
Diameter= 2 ×radius
radius of globe
= 14 ÷2
= 7 inches
Volume of globe
[tex] = \frac{4}{3} π {(7}^{3} ) \\ = 1436.8 \: in^{3} \\ (nearest \: tenth)[/tex]
Step-by-step explanation:
We have given that diameter of globe (sphere) is 14 inches,Then it's radius is 14/2 = 7 inches :]To find the volume of sphere we have to use the given below formula :]
[tex] \boxed {\underline{ \underline{\bigstar\:\: \sf Volume \: of \: sphere = \dfrac{4}{3} \pi r^3 \: \: \bigstar}}} \\ \\ [/tex]
☯ [tex]\underline{\boldsymbol{According\: to \:the\: Question\:now :}} [/tex]
[tex]:\implies \sf Volume \: of \: sphere = \dfrac{4}{3} \times 3.14 \times 7 \times 7 \times 7 \: \: \bigg \lgroup \bf{putting \: \pi = 3.14} \bigg \rgroup \\ \\ [/tex]
[tex]:\implies \sf Volume \: of \: sphere = \dfrac{4}{3} \times 3.14 \times 343 \\ \\ [/tex]
[tex]: \implies \underline{ \boxed{ \sf Volume \: of \: sphere = 1436.0267 \: cubic \: inches}} \\ [/tex]
[tex] \tan(x ) = \frac{10}{60} [/tex]
How do I solve this?
tan(x) = 10/60
tan(x) = 1/6
tan(x) = a -> x = arctan(a) + πn
x = arctan(1/6) + πn
x = 0.165 + πn

Maria babysat for 6 hours on Tuesday, 3 hours on Thursday, and 4 hours on Saturday.
If Maria is paid $6.00 per hour, how much money did she make on these three days?
Answer:
First, convert 150% to the equivalent decimal 1.50 by dropping the percent sign and moving the decimal two places to the left. Then, multiply 9 by 1.50 to get 13.50. Maria now makes $13.50 per hour.
Step-by-step explanation:
I took the test and this is the sample answer
The required earnings for Maria for the three days is $78.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

18- 12y = -22 -7y solve for y
Answer: y=8
Step-by-step explanation:
To solve for y, you want to use algebraic properties to isolate y.
18-12y = -22-7y [add both sides by 7y]
18-5y=-22 [subtract both sides by 18]
-5y=-40 [divide both sides by -5]
y=8
Now, we know that y=8.

Answer: Choice A) $0.20
=======================================================
Explanation:
The store bought the batch for $100, and sold that same batch for $150. The profit of the entire batch is 150-100 = 50 dollars.
Divide this over 250 to get 50/250 = 0.20 dollars.
Their profit is $0.20 per pastry (ie 20 cents per pastry).
-------
You can think of it like this
50 dollar profit = 250 pastries
50/250 dollar profit = 250/250 pastries (dividing both sides by 250)
0.20 dollar profit = 1 pastry
That last equation tells us one pastry yields a profit of $0.20 or 20 cents.
Answer:
$0.20
Step-by-step explanation:
If the purchased is $100 for 250 pastries, then 1 ipastry at purchase is:
$100=250
? = 1
1×100/250 = $0.40 ( at purchase)
Then when resold, the profit is:
if 250 pastries= $150
1 pastry=?
$150× 1/ 250= $0.60
s0, the profit will be $0.60 - $0.40 = $0.20

what is 7(1 - 8n)???
Answer:
7-56n
Step-by-step explanation:
By using the distributive property you multiply the 7 to the 1 which equals 7. Then you distribute the 7 to the -8n which gives you -56n becaus emultiplying a negative and a possitive gives you a negative.
The required solution is -56n+7.
It is required to find the solution.
What is algebra?A part of mathematics in which letters and other general symbols are used to represent numbers and quantities in formulae and equations.
Given:
Rearrange terms
7(1 - 8n)
=7(-8n+1)
Then distribute by multiplying 7 we get,
-56n+7
Therefore, the required solution is -56n+7.
