The area of a circle with a diameter of 20 meters using 3.14 as an approximation for pi is 314 m^2. A = pi(r^2); r = 20/2 = 10; A = 3.14(10^2); A = 314

JoyFreak, I'm starting to get the feeling that you're just guessing on all these math questions I'm correcting for you...Please refrain from doing that. If you cannot answer a question, pass it to another Expert.

The answer is C.25. If you want to take a good stab at it, add 100+50. The multiply that 150 by all the choices individually then divide that answer by 2. 150*25=3750....3750/2=1875. Your answer.
