The volume of a cylinder is 7271 cmIf the radius is 3 cm, what is the height
of the cylinder?
3 cm
O A 40m
B 3C
Answers
Answer:
3cm approx
Step-by-step explanation:
Given data
Volume= 72cm^3
Radius=3cm
Required the height
The expression for the volume is
Volume= πr^2h
substitute
72=3.142*3^2*h
72=28.278h
h= 72/28.278
h=2.54
Hence the height is 3cm approx

Answer:
(4, -10), (4, 6)
Step-by-step explanation:
The vertical diameter is on the vertical line through the center of the circle. That line is x=4.
The square of the radius is 64, so the radius is √64 = 8. The y-coordinate of the diameter end points will be the y-coordinate of the center ±8.
So, the points of interest are ...
(4, -2±8) = (4, -10) and (4, 6) . . . . end points of the vertical diameter

Then divide by 3
63/3 = 21
256-193=63
63/3=21

Answers
Answer:
[tex]h = - 12[/tex]
Step-by-step explanation:
1) Add 1 to both sides.
[tex] \frac{h}{6} = - 3 + 1[/tex]
2) Simplify -3 + 1 to -2.
[tex] \frac{h}{6} = - 2[/tex]
3) Multiply both sides by 6.
[tex]h = - 2 \times 6[/tex]
4) Simplify 2 × 6 to 12.
[tex]h = - 12[/tex]
Therefor, the answer is h = -12.
Answer:
h = - 12
Step-by-step explanation:
Add 1 to both sides of the equation
ℎ/6 − 1 + 1 = − 3 + 1
Simplify
ℎ/6 = − 3 + 1
h/6 = -2
Multiply all terms by the same value to eliminate fraction denominators
6 ⋅ ℎ/6 = 6 ( − 2 )
Cancel multiplied terms that are in the denominator
ℎ = 6 ( − 2 )
Multiply the numbers
ℎ = − 12

Answer:
102
Step-by-step explanation:
You have to substitute x and y. Since x = 3 and y = 4, you would write the equation as 6(3) + 21(4). Multiply that, and you get 18 + 84. Add that together, and you get the answer 102.
Answer: 102
Step-by-step explanation: 6x + 2y
6(3) + 21(4)
18 + 84

Step-by-step explanation:
Let a = 1/x
b = 1/y
Then the equations are

-10a - 16b = -66

b = 4 5a + 8(4) = 33
5a + 32 = 33
