The formula for the area of a circle is A= ar?m where A is the area and r is the radius. The subject of the formula is A. Rearrange the formula to make r the subject.

Hi there! :)

Step-by-step explanation:

Formula for the area of a circle:

Rearrange the equation in terms of "r":

Divide 'π' from both sides:

Take the square root of both sides:

Since 8/26 want to play soccer and 12/26 want to play basketball, you would add 8/26 and 12/26 to get 20/26, then you would subtract 20/26 from 26/26, leaving you with 6/26 of the students wanting to play baseball.

note: if the question wants you to simplify you would divide both your numerator and your denominator by 2 to get 3/13 as your final simplified answer.
