George is given two circles, Circle O and circle X, as shown. If he wants to prove that the two circles are similar, what would be the correct fourth step in his proof? Given: The radius of circle O is r, and the radius of circle X is r'.

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
