By a 6th grader-----------------------------------------------------------------------------------------------find # that is a common multiple of 2 and 7 - the denominators ( 14 )
then do:
denominator stays same - if improper fraction change to mixed #
1 times 7 = 7 + 3 times 2 = 6
2 times 7 = 14 7 times 2 = 14
6 + 7 over 14 is 13 over
14
if possible and needed - change to simplest form
The answer is 3.5 to the question
A=pi r^2
=3.1416 *14*14
615.7536
* your b & d choices are the same
You want to get the t to itself so you would add 13 to 13 which would give you 26, t=26
