The volume of the sphere is 7241.143.
What is volume?
Volume is the amount of three-dimensional space occupied by an object, substance, or closed surface.
Formula of volume of sphere = [tex]\frac{4}{3} \pi r^3[/tex]
Given
Radius of sphere = 12cm
volume of sphere = [tex]\frac{4}{3} \pi r^3[/tex] = [tex]\frac{4}{3}\ \frac{22}{7}[/tex] 12×12×12
= [tex]\frac{152064}{21}[/tex]
= 7241.143
Hence, The volume of the sphere is 7241.143.

i need help with geometry
Answer:
C.
Step-by-step explanation:
I. If angles 1 and 2 are supplementary, then the sum of their measures is 180.
II. m<1 = 110
Now we can find the measure of <2.
m<1 + m<2 = 180
110 + m<2 = 70
III. m<1 + m<2 + m<3 = 180; m<3 ≠ 0
We know the measures of angles 1 and 2, s we can find the measure of angle 3.
110 + 70 + m<3 = 180
180 + m<3 = 180
m<3 = 0
The measure of angle 3 must be zero according to statements I and II. According to statement III, the measure of angle 3 is not zero.
Answer: C.
7,10,3 how do I find the least common multiple
Answer:
Step-by-step explanation:
Usually you do it by factoring into primes. But this choice of numbers has no common primes, so all three make up the LCM
7 * 10 * 3
210 = LCM
LCM of 4 10 and 12
4: 2 * 2
10: 2 * 5
12: 2*2*3
LCM: 2 * 2 * 3 * 5 = 60
If you don't find the LCM then the answer would be 480
Answer:
210
Step-by-step explanation:
When finding the LCM(least common multiple) you need to factor each number into the product of prime number also called finding the prime factorization. Both 7 and 3 are prime, so they do not need to be factored further. However, 10 can be factored into 5 x 2.
3 - 3
7 - 7
10 - 5 x 2
By looking at the factors above, you notice none of them are the same, so none of the numbers share factors. This means you can just multiply all the factors to get the LCM:
3 x 7 x 5 x 2

If the area of trapezoid is 100 cm, what is the perimeter of the trapezoid?
Answer:
Step-by-step explanation:
If the area of trapezoid is 100 cm²what is the perimeter of the trapezoid?
Area of a trapezoid = 100cm
= 1/2(a + b) × h = 100cm²
Perimeter of a trapezoid = a + b + h
Mrs. Rodger got a weekly raise of $145. If she gets paid every other week, write an integer describing how the raise will affect her paycheck.
Answer:
Let the 1st paycheck be x (integer).
Mrs. Rodger got a weekly raise of $ 145.
So after completing the 1st week she will get $ (x+145).
Similarly after completing the 2nd week she will get $ (x + 145) + $ 145.
= $ (x + 145 + 145)
= $ (x + 290)
So in this way end of every week her salary will increase by $ 145.

Two cars drive on the same highway in the same direction. The graphs show the distance, d, of each one as a function of time, t. Which car drives faster? Explain how you know.
Answer:
Car BStep-by-step explanation:
The equation for the speed is:
s = d/tFrom the equation we see for the same t the speed is greater if d is greater.
We can show that if add a vertical line to a graph and compare the d- values of the intersection of the vertical line with the graphs of the cars.
It obvious the graph of the Car B will have a greater d- value.
It means that Car B has a greater speed so it is faster that Car A.
Noah says, "If I try to write 100 expanded, it should have zero factors that are 10, so it must be equal to 0." Do you agree? Why or why not?
Answer:
Disagree
Step-by-step explanation:
10^0
According to the laws of indices, anything raised to the power of 0 will equate to 1. Therefore, based on this established mathematical principle, Noah's assertion about 10^0 being equal to 0 is false.
Hence, I disagree.

A lenght of wire is bent to make a square of side 3.2 cm a: what is the length of wire in the square B: if the wire is silver costing 50 naira per centimetre what is the cost of the square C: 20 of the squares are linked together to make a necklace what does it cost to make the necklace
Answer:
12.8cm
640 naira
12,800 naira
Step-by-step explanation:
length of the wire is equal to the perimeter of a square
perimeter of a square = 4 x length
4 x 3.2 = 12.8 inches
cost of the square = length of the wire x 50
12,8 x 50 = 640
20 x 640 = 12800

Answer:
EFG = 104°
GFH = 76°
Step-by-step explanation:
The sum of a linear pair is always equal to 180°
So lets solve for the variable n
2n + 32 + 4n + 16 = 180
6n + 48 = 180
6n = 132
n = 22
So now we know N
EFG = 4n + 16
EFG = 88 + 16
EFG = 104°
GFH = 2n + 32°
GFH = 44 + 32
GFH = 76°

Is the function below linear or non linear? y = 5 + 3(x-4)
Answer:
Linear
Step-by-step explanation:
The rule is that linear equations must have exponents of 1 (a sloped line) or 0 A verticle or horizontal line). This function can be simplified to
y = 3x - 12 + 5 = 3x - 7 which is the standard form of a linear equation
y - mx + b where m is the slope and m is the y intercept.

Answer:
∠ 1 = 130°, ∠ 2 = 50°
Step-by-step explanation:
∠ 1 and 130° are alternate angles and congruent, so
∠ 1 = 130°
∠ 2 and 130° are same- side interior angles and are supplementary, so
∠ 2 + 130° = 180° ( subtract 130° from both sides )
∠ 2 = 50°
Answer: it is 130 and 50
Step-by-step explanation: Honestly, they already gave one angle so it is a HUGE giveaway. 180-130 is 50, so the answers are 130 and 50.

Use r = 2 and r = 5 to determine if the two expressions are equivalent. r + 4(2 + r) – 12 8 + 2r – 6
Answer:
No they are not equivalent
Step-by-step explanation:
The given expressions are r + 4(2 + r) – 12, and 8 + 2r – 6
Let us first put r= 2 in the above expression
2+4(2+2)-12= 6
and 8+2(2)-6 = 6
Now let us put r=5 in the above two expressions
5+4(2+5)-12 = 21
similarly, 8+2(5)-6 = 12
Clearly, the two expressions are not equivalent when we put r=2 and r=5 as the values coming are different.
Answer:
the first expression is 6.
the second expression is 12.
they are NOT equivalent.
