Answer:
Value is 15 and measure is 151
What you would have to do is take the 18 and double it because 50% doubled is 100% so when you double 18 it is 36
If the radius of the circle is 4 than the area would be 50.27.
If you are saying that 4 is the diameter, than divide that by 2 to get the radius which is 2. The area for this would be 12.57.
I don’t know which one you mean but hope this helps :))
