How do i find the radius of a cylinder with only surface area and height

Dima020 [189]

Answer:

The area of a circle is defined as A=pi*R*R. To find the radius, first divide A/pi. The answer would be the square of the radius; therefore, the square root of A/pi is the radius of the cylinder. Volume is defined as V=pi*R*R*H, or V=A*H. Dividing the volume by the area V/A would result in the height of the cylinder.

1/3x * 6 = -8<br><br> it says solve

bulgar [2K]

Subtract 6 from both sides, you get 1/3x=-14

Now multiply both sides by there, hence x=-42

Write a function that represents the situation. Find the balance A in the account after the given time period t. $6200 deposit t

MaRussiya [10]

Answer:

$A=P(1+r)^t$
$\$7029.46$

Step-by-step explanation:

As this is the case of exponential growth, we can use the function

$A=P(1+r)^t$

Here A is function of t, where A gives the balance after time t.

P = initial deposit,

r = rate of change or rate of interest,

$6200 deposit that earns 8.4% annual interest compounded monthly for 18 months.

So,

P = $6200,

r = 8.4% annual = $\dfrac{8.4}{12}\%$ monthly = $\dfrac{0.084}{12}$ monthly (as interest compounded monthly)

t = 18 months,

Putting all the values,

$A=6200(1+\frac{0.084}{12})^{18}$

$=6200(1+0.007)^{18}$

$=6200(1.007)^{18}$

$=\$7029.46$

Answer:

from the given info

you can know that there were 16 red ones. (2/3)*24

and 8 green apples

and her classmates ate 3/4 of red ones i.e.

(3/4)*16

=12

and 1/2od green

i.e.

(1/2)*8

=4

and now the total eaten apples

= 12+4

=16

and the remaining number are

24-16

=8

Write your answer in simplest radical form

mars1129 [50]

Answer:

q = $\sqrt{2}$

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin30° = $\frac{1}{2}$ , then

sin30° = $\frac{opposite}{hypotenuse}$ = $\frac{q}{2\sqrt{2} }$ = $\frac{1}{2}$ ( cross- multiply )

2q = 2 $\sqrt{2}$ ( divide both sides by 2 )

q = $\sqrt{2}$
