Answer 7

wait i think its 18.80 because it says "Express your final answer to the nearest hundredth."

Answer 8

Well, i suck at rounding to hundreths so i wont be able to do that for you...

But, to find a semi circle perimeter you take the normal perimeter formula (2
π
r) and divide by 2.

Answer 9

hmm so π x 2 = 6.28 and then 6.28 divided by 2 is 3.14

Answer 10

6 x 2 x 3.14 = 37.68

37.68 / 2 = 18.84 like you said :)

I am sorry i can't be of help with the rounding to hundreths, let me see if i can google that for you real quick...

Answer 11

kk

Answer 12

I would wait to get it confirmed, but i would say 18.84 is dine because the 4 is in the hundredths place. if it was 18.842 then you would round to 18.84
