Answer:

The answer to your question is 9 cm

Step-by-step explanation:

Data

slant height = 15 cm

height = 12 cm

radius = ?

Process

To solve this problem, use the Pythagorean theorem. The slant height is the hypotenuse, the height is the long leg and the radius is the short leg.

             c² = a² + b²

           slant height² = height² + radius²

-Solve for radius

           radius² = slant height² - height²

-Substitution

           radius² = 15² - 12²

-Simplification

            radius² = 225 - 144

            radius² = 81

-Result

            radius = 9 cm

Answer:

Both volumes are the same

Step-by-step explanation:

Volume of cylinder = \pir^{2} h

r = radius

h = height

Since area of the circle is given on top,

Area of a circle = \pir^{2}

We know the area is 12

12 = \pir^{2} (we need to find r)

r = \sqrt{\frac{12}{\pi} }

r = 1.954

Now we can find the cylinder's volume:

Volume of cylinder = \pi(1.954)^{2} (6)

Volume of cylinder = 72

To find the volume of the cuboid, we use

Volume of cuboid = lwh

l = length

w = width

h = height

Volume of cuboid = 6 x 4 x 3

Volume of cuboid =  72

This proves that both the volumes are the same.

∠1 ​ and ∠2 are supplementary.
Rasek [7]
By definition, supplementary angles are those whose sum is 180°

Therefore, ∠2 = 180 - ∠1
2x + 4 = 180 - 124
2x = 52
x = 26°

Nia solved the equation -1.98 = 5.2v + 13.1. Her answer was v = -2.9. She is fairly confident about her answer, but wants to do
valina [46]

Answer:

substitute for v, when v = -2.9

Step-by-step explanation:

-1.98=5.2v+13.1

subtract 13.1 on both sides.

-15.08=5.2v

divide by 5.2 to isolate v

\frac{-15.08}{5.2} = \frac{5.2v}{5.2}

-2.9=v

substitute for v

-1.98=5.2(-2.9)+13.1

-1.98=-15.08+13.1

-1.98=-1.98

Which of the following is the balance for a single $2700 deposit in an account with an APR of 4.5% that compounds interest month
Zanzabum

The future amount is $3697.52, if a a single $2700 deposit in an account with an APR of 4.5% that compounds interest monthly and is invested for 7 years.

Step-by-step explanation:

The given is,

                     A single deposit amount - $ 2700

                                                       APR - 4.5%

                                            ( Compounded monthly )

                                                    Period - 7 years

Step:1

                 Formula to find future amount with an APR compounded monthly,

                                                          A = P(1+\frac{r}{n})^{nt}.......................(1)

                Where, A - Future amount

                             P - Initial deposit

                              r - Interest rate

                             n - Number of compounding in a year

                             t - No.of years

                From given,

                         P = $ 2700

                          r = 4.5%

                          n = 12                   (∵ For monthly n becomes 12 )

                           t = 7 years

                   Equation (1) becomes,

                                                           = 2700(1+\frac{0.045}{12})^{(12)(7)}

                                                           = 2700(1+0.00375)^{84}

                                                           = 2700(1.36945)

                                                           = 3697.52

                                                       A = $3697.52

Result:

              The future amount is $3697.52, if a a single $2700 deposit in an account with an APR of 4.5% that compounds interest monthly and is invested for 7 years.
