The increase is $5000-$4000=$1000. The ratio of this increase to the original price is
$1000
-------- = 1/4 (no units of measurement here)
$4000
Each coin will either land as a head or a tail. - 2 possible results.
for 5 coins its 2*2*2*2*2 = 32 different results.
The correct answer is 10,000
C = 2 pi r
C = 2 x 3.14 x 4.4
C = 27.632
C = 27.6 to nearest tenth.
answer
C = 27.6 cm
hope it helps
