What is the volume of the sphere given below? if necessary, round your answer to two decimal places.
Marrrta [24]
The formula for volume of a sphere is V=(4pi*r^3)/3.
Plugging in 12 for r we get
V=(4pi*(12)^3)/3
V=(4pi*1728)/3
V=(6912pi)/3
V=2304pi
Round to 2 decimal places: 7238.23
Final Answer:
7238.23 cubic units.
Hope I helped :)

Which of the following proportions is TRUE? a. 1:4 = 2:5 b. 6:9 = 10:12 c. 5:11 = 15:30 d. 2:7 = 4:14
Vlad1618 [11]
2:7 = 4:14 because each is equal to 2/7. If you simplify 4:14 by dividing by 2, it simplifies to 2:7.

Need help answering this question!!!!
Y_Kistochka [10]
For this case we use the following formula
Area of Sector = Area * radians of sector / 2 * pi radians
Where,
Area: it is the area of the complete circle.
We have then:
Area = pi * r ^ 2
Area = pi * (6) ^ 2
Area = 36pi
Substituting values:
5pi = 36pi * radians of sector / 2 * pi
Clearing:
radians of sector = ((5pi) * (2pi)) / (36pi)
radians of sector = (10pi ^ 2) / (36pi)
radians of sector = (10pi) / (36)
radians of sector = (10/36) pi
radians of sector = (5/18) pi
in degrees:
(5/18) pi * (180 / pi) = 50 degrees
Answer:
The measure of the central angle is:
50 degrees

A linear equation exists for the following sets of ordered pairs: {(-1, 1), (0, 3), (-1/3, 7/3)}. The rule for the linear equati
kaheart [24]

Answer:

Part 1) y=2x+3

Part 2) The equation satisfy the set of coordinates (see the explanation)

Step-by-step explanation:

step 1

Find the linear equation

The rule for the linear equation states that y is three more than twice x.

so

The variable y is equal to the number 2 multiplied by x plus the number 3

y=2x+3

step 2

Prove that the equation satisfies the set of coordinates

substitute the value of x and the value of y in the linear equation and then compare the results

a) (-1, 1)

1=2(-1)+3

1=1 ----> is true

so

The equation satisfy the ordered pair

b) (0, 3)

3=2(0)+3

3=3 ----> is true

so

The equation satisfy the ordered pair

c) (-1/3,7/3)

7/3=2(-1/3)+3

7/3=7/3 ----> is true

so

The equation satisfy the ordered pair

therefore

The equation satisfy the set of coordinates
