Answer:
Question one 186
Question two 240
Step-by-step explanation: You multiply the variable (the letter) by the number that the person is using
C = to squares diagonal length
Pythagoras theorem: a^2 + b^2 = c^2
5^2+5^2=c^2
25+25=c^2
50=c^2
square root so c would be about 7.071
Since the diagonal is less than the diameter of the circle, the square will fit inside without touching the edge
