Find the area of a circle givin the diameter of 12. Use 3.14 for pi.

valina [46]

Answer:

113.04 units^2

Step-by-step explanation:

The area of a circle can be found using:

$a=\pi r^{2}$

First, we need to find the radius, since we have the diameter.

Radius

The radius is half the diameter, or

r=d/2

We know the diameter is 12, so we can substitute that in

r=12/2 Divide

r=6

Area

Now we know the radius and can substitute it into the area formula

$a=\pi r^{2}$

$a=\pi 6^2$ Solve the exponent

$a=\pi 36$

Substitute 3.14 in for pi

a=3.14*36 Multiply

a=113.04

We aren't given a specific unit, so we can say the area is

113.04 units^2

Item 8 A container has peppermint gum and spearmint gum. There are 18 pieces of peppermint gum in the container and the ratio of

Montano1993 [528]

Answer:Number of Spearmint gum = 27 pieces

Step-by-step explanation:

step 1

Let the total number of peppermint gum and spearmint gum in the container = X

Ratio of peppermint gum to spearmint gum= 2 : 3.

Total ratio = 2+ 3=5

Step 2

we were given that peppermint gum= 18 pieces , so total number of gums will be calculated as

Ratio of peppermint/ Total ratio x Total number of gums = Number of peppermint

2/5 x X= 18

X=(18X 5) / 2 = 45

X= Total number of gums = 45

Number of spearmint gum will now be

Ratio of spearmint/ Total ratio x Total number of gums = Number of spearmint

3/5 x 45= 27

Therefore Number of Spearmint gum = 27 pieces

Andrea has a jug containing 1.5 liters of chocolate milk. She fills one cup with 250 milliliters and another cup with 0.6 liters

aleksklad [387]

Answer:

650 milliliters.

Step-by-step explanation:

Amount in the Jug = 1.5 * 1000 = 1,500 mls.

She pours out 250 mls and 0.6 * 1000 = 600 mls

The amount left = 1500 - 250 - 600

= 650 milliliters.

One side of a triangle is twice the shortest side. The third side is five feet more than the shortest side. The perimeter is 17

guajiro [1.7K]

Answer:

3, 6 and 8

Step-by-step explanation:

In order to solve the problem, we call:

$a$ = length of the 1st side of the triangle

$b$ = length of the 2nd side of the triangle

$c$ = length of the 3rd side of the triangle

From the text of the question, we know that:

- One side of a triangle is twice the shortest side --> we can write this as

$b=2a$ (1) (assuming "a" is the shortest side)

- The third side is five feet more than the shortest side. -->

$c=a+5$ (2)

- The perimeter is 17 feet -->

$a+b+c=17$ (3)

So now we have 3 equations with 3 unknown variables. Substituting (1) and (2) into (3) we can find the value of "a", the shortest side:

$a+2a+a+5=17\\4a=17-5=12\\a=3$

And so

$b=2\cdot 3=6\\c=3+5=8$

So the lengths of the 3 sides are 3, 6 and 8.

Please help me with this :(

dusya [7]

Answer:

I think the way they are telling is that the triangle will move to the third quadrant,

If so, then the coordinates of P'Q'R' will just be the negative of PQR.
