Answer:

1:28.26

2:28.30

Explanation:

since Pi (
\pi) is 3.14 and the radius is 9 in we multiply:


\pi

x 9

28.26 and then we have too round for question 2 so we use the "5 or more go up 4 or less go down" rule and since theres a decimal were rounding the 0.26, so we take away the 0.2, now we have 0.06, and since 6 is 5 or more we round up turning it to 0.1, Now we bring back the 0.2 and add them to make 0.3 or 0.30, lets not forget about the 28 and 28 + 0.30 = 28.30 or 28.3 since there is no need for a zero to be there.
