Assuming you would like to find the volume . . . . .

Answer:

113.04

Step-by-step explanation:

To find volume, the formula is pi x r^2.

Let's replace the values.

3.14 * 6^2

Note that the radius is 6 since r = 1/2 d.

Now we just need to solve.

= 3.14 * 36

= 113.04

Assuming you want to solve for surface area . . . . .

The formula is long but it is:

SA =2πrh+2πr^2

Replace the values.

SA = 2 (3.14)(6)(11.5) + 2 (3.14)(6) ^2

Simplify.

6.28 (69) + 6.28 (36)

= 433.32 + 226.08

= 659.4

Answer:

900 black and white copies are printed.

Step-by-step explanation:

Given:

For every 9 black and white copies printed there are 2 color copies printed.

If there are 200 color copies printed.

Now, to find the number of black and white copies are printed.

Let the number of black and white copies printed be $x.$

As given, for every 9 black and white copies printed there are 2 color copies printed.

So, 9 is equivalent to 2.

If there are 200 color copies printed.

Thus, $x$ is equivalent to 200.

Now, to solve by using cross multiplication method:

$\frac{9}{2} =\frac{x}{200}$

By cross multiplying we get:

$1800=2x$

Dividing both sides by 2 we get:

$900=x$

$x=900.$

Therefore, 900 black and white copies are printed.

Kitara has 100 quarters and dimes. Their total value is $19. How many of each coin does Kitara have?

Sedbober [7]

Q + d = 100 so q = 100 - d
0.25q + 0.10d = 19

substitute q = 100 - d into 0.25q + 0.10d = 19

0.25q + 0.10d = 19
0.25(100 - d) + 0.10d = 19
25 - 0.25d + 0.10d = 19
-0.15d = -6
d = 40

q = 100 - 40 = 60

answer
Kitara has 60 quarters and 40 dimes
