The area of the circle is 144π m2

What is the diameter of the circle?

Step-by-step explanation:

Remember that

Area of Circle =

They told us that for this circle, the area is

If you put it back into the formula for area of a circle we get:

Area of Circle =

Divide both sides by .

144 =

Now we want to solve for r (r = radius).

You need to square root each side

So now we know the radius, metres

Also remember that

Diameter =

So,

Diameter = 2 times 12 = 24 metres

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.

this is false ^.^ lol
