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

6 hours 48 min

step-by-step explanation:

68÷5=13.6

13.6×30=408min=6 hours 48 min.

hope to and hope that my answer is brainliest.(follow me )

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
