If one circle has a diameter = 6 inches and the other has a diameter = 8 inches, what is the ratio of the radii? Use the rule of
ratios to find the ratio of the Areas.
1 answer:
Answer:
3 : 4 ratio of radii
9 : 16 ratio of areas
Step-by-step explanation:
The ratio of radii is the same as the ratio of diameters:
one : the other = 6 :8 = 3 : 4
__
The ratio of areas is the square of the ratio of radii:
one : the other = 3² : 4² = 9 : 16
