Look at 4 km and 4,000 m. Recall that 1 km = 1000 m. Thus, 4 km = 4000 m.
So 4 km and 4,000 m are equivalent.
Look at 3 lb and 48 oz. Note that 16 oz = 1 lb, and so 48 oz = 3 lb.

Answer:
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
