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

e) none of the above because the measure of angle cba is 101°
