A sphere and a cylinder have the same radius and height. The volume of the cylinder is 11ft^3
Which equation gives the volume of the sphere?
^(Answers above on picture)^
9514 1404 393
Answer:
(d) 2/3(11)
Step-by-step explanation:
The height of the cylinder is h=2r, so the volume of the cylinder in terms of radius is ...
V = πr^2·h = πr^2·(2r) = 2πr^3
The volume of the sphere is given by the formula ...
V = (4/3)πr^3
So, the ratio of the sphere volume to the cylinder volume is ...
sphere volume / cylinder volume = ((4/3)πr^3)/(2πr^3) = (4/3)/2 = 2/3
That is, the sphere volume is ...
sphere volume = (2/3) × (cylinder volume)
V = (2/3)(11)

Answer:
Possibilities
2.4 or 2 2/5
2 remainder 14
Step-by-step explanation:
First we can solve with long division...
35 goes into 84 2 times....
So......we would do 84 - 70 to get the remainder as 14.
So....one possibility to the answer is 2 remainder 14.
Another way.....
We can do the same steps we did above but we can continue and turn the number into a decimal. So.... Since we know that 35 doesn't go into 14 we can add .0 after 14 to get this...
14.0 ÷ 35
Next we pretend there is no 0 after the decimal and we pretend that the number is actually 140. So, 140 ÷ 35 = 4. Since we pretended that 14.0 was actually 140, we have to put one number behind the decimal point which in this case is 4. So our final answer is 2.4 or 2 2/5
Hope this Helps!!! :)

The area of a rectangular field is 6831 m If the length of the field is 99 m, what is its width?
Answer:
The width is 69m
Step-by-step explanation:
Set it up in a equation, W x 99 = 6831. So first thing to do is get the letter by its self. So you will do the opposite of multiplication. And what you do to one side you do to the other so you divide 6831 by 99. And you get W = 69
Answer:
Step-by-step explanation:
Area of rectangular field = length × width 99×w=6831
w = 6831/99
w=69m

A watermelon seed is 0.4cm long. How far would a line of 126 stretch?
Answer:
0.504m
Step-by-step explanation:
First, we would multiply 0.4cm by 126 watermelon seeds to find the length of the line in cm.
0.4*126
= 50.4cm
Therefore, the line of watermelon seeds stretches 50.4cm.
Now, because the question wants us to type the answer in meters, we must convert 50.4cm into meters. We do this by dividing 50.4 by 100 since 100cm makes up 1 meter.
50.4/100
= 0.504m
Therefore, the line of watermelon seeds stretches 0.504m.
I hope this helps!

You draw a rectangle with vertices at (-3.5,3), (3.5,3), (3.5. - 3), and (-3.5. - 3). What is the
perimeter and area of the rrectangle?
What is the perimeter and area of the rectangle
Answer:
P = 26 units
Area = 42 square units.
Step-by-step explanation:
Notice that the points are showing a rectangle with length with a horizontal segment on the coordinate plane that goes from -3.5 to 3.5 (7 units in length), and width a vertical segment from -3 to 3 (6 units in length).
Therefore the rectangle's perimeter (P) is:
P = 2 L + 2 W = 2* 7 + 2 * 6 = 14 + 12 = 26 units.
The area of the rectangle is given by:
Area = L * W = 7 * 6 = 42 square units.

What is 10/8 written as a decimal?
Answer:
10/8= 1.25
Step-by-step explanation:
10 divided by 2=5 8 divided by 2= 4=5/4
5÷4=1.25
The fraction 10/8 as the decimal equivalent is A = 1.25
What are decimal numbers?The decimal numbers can only be expressed as fractions since they contain a fractional component. The accepted method for representing both integer and non-integer numbers is the decimal numeral system. There are 10 single-digit numbers in the decimal system:
0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. After the number 9, comes 10, then comes 11, then 12, and so on. Each time the digit to the right exceeds 9, the number on the left is increased by 1.
Given data ,
Let the decimal number be represented as A
Now , the value of A is
Let the fraction be represented as n
The value of n = 10 / 8
On simplifying , we get
The value of n in the decimal equivalence is given by dividing the number 10 by 8
So , A = 10 ÷ 8
A = 1.25
Therefore , the value of A is 1.25
Hence , the decimal number is 1.25

8(7q+6p+11) please help me
Answer:
56p + 48q + 88
Step-by-step explanation:
When you see parentheses in math, it usually means that you are distributing (multiplying).
So here you would multiply everything inside the parentheses by 8.
7q x 8 = 56q
6p x 8 = 48p
8 x 11 = 88
56q + 48p + 88

Mrs. Phillips bought 1.5 pounds of ground beef from Kroger. She paid a total of $6.75 for the ground beef. What was the price per pound?
Answer:
Price per pound is $4.50
Step-by-step explanation:
Price per pound = $6.75 / 1.5lb = $4.50/lb
Answer:
Price per pound of ground beef is $4.5
Step-by-step explanation:
Price of 1.5 pounds of ground beef = $6.75
We need to find price per pound of ground beef.
Solving:
For finding cost of 1 pound of apples, we will divide cost of 1.5 pounds of ground beef by 1.5. i.e
Price of 1.5 pounds of ground beef = $6.75
Price of 1 pounds of ground beef = $6.75/1,5
= $ 4.5
So, price per pound of ground beef is $4.5
