I think the answer is 2,612.48 because if you multiply the radius, 80 by itself you get 640. Then if you multiply 640 by 3.14 and then multiply the product by 1.3 you get 2,612.48.
18/25, 51/75, 33/50, 13/20, 3/5
The simplified form is: =4p2−18p+8
Step by Step:
(4p−2)(p−4)
=(4p+−2)(p+−4)
=(4p)(p)+(4p)(−4)+(−2)(p)+(−2)(−4)
=4p2−16p−2p+8
=4p2−18p+8
The Law of Conservation states that energy can neither be created or destroyed. So I believe the answer should be A, since the Light energy is being converted and not destroyed and then made again
