If the circumference of the base=126 cm and h=10 cm, find the volume

The formula for the volume of a cylinder (I'm assuming this is a cylinder) is
V=Pi*r^2*h

You know the circumference which is 126
Circumference C=2*Pi*r, so you can determine r
126=2*Pi*r
r=20.05cm

Now go back and substitute your numbers in the original equation:
V=Pi*r^2*h
V=12633.72cm^3

Answer:

(1,0)

(-2,3)

(5,24)

Step-by-step explanation:

To solve this you can can just plug in the x and y values and see which work

y = x²-1

Lets test (0,1):

1 = 0²-1

1 = -1

This pair <em>does not</em> work, because 1 does not equal -1

Lets test (1,0):

0 = 1²-1

0 = 0

This <em>does</em> work, because 0 equals 0

Lets test (3,5):

5 = 3²-1

5 = 9 - 1

5 = 8

This pair <em>does not</em> work, because 5 does not equal 8

Lets test (5,24):

24 = 5²-1

24 = 25 -1

24 = 24

This pair <em>does</em> work, because 24 equals 24

Lets test (-2,3):

3 = (-2)²-1

3 = 4-1

3 = 3

This pair <em>does</em> work, because 3 equals 3

Lets test (-4,-17):

-17 = (-4)²-1

-17 = 16 - 1

-17 = 15

This pair <em>does not</em> work, because -17 does not equal 15

So the pairs that are on the graph are:

(1,0)

(-2,3)

(5,24)

Zepler [3.9K]

Answer:

(4^-3)(x^-3) y^(18)

or

y^18/ (64 x^3)

Step-by-step explanation:

(4xy^-6)^-3

Distribute the exponent to all terms in the parentheses

(4^-3)(x^-3) (y^-6)^-3

a^ b^c = a^ (b*c)

(4^-3)(x^-3) y^(-6*-3)

(4^-3)(x^-3) y^(18)

If we do not want negative exponents

a ^ -b = 1/ a^b

y^18/( 4^3 x^3)

y^18/ (64 x^3)
