Area of a circle is

. The first one, a, the radius squared is 8*8=64. So

. If you multiply in pi as 3.14, you'll have 200.96 square inches. The second one, b, the radius squared is 10*10=100. So

square kilometers. If you multiply in pi as 3.14 you'll have 314 square kilometers. The third one, c, the radius squared is 14*14=196. So

. Or you could multiply in pi as 3.14 to get 615.44 yd squared. For the last one, d, the radius squared is 22*22=484 cm. Therefore,

, or multiply in 3.14 for pi to get 1519.76 cm squared. There you go!
Negative i believe is the correct answer
Answer:
I believe the answer is (A)
Subtract the total of the 3 fish she is buying from the amount of money she has:
85 - (12 + 13 + 14) = 85 - 39 = 46
She has $46 to spend on crabs.
Divide the amount she has to spend by the price on one crab:
46 / 8 = 5.75
Since it isn't a whole number you need to round down, since she cant buy 0.75 of a crab.
She has enough money to buy 5 crabs.
Answer:

Step-by-step explanation:
1. Add the equations. The y's cancel out.

2. Embed x in either equation and find y.
