Answer:
3. 14 cm
Step-by-step explanation:
Solve for radius first using the equation for circumference:
C = 2πr
44 = 2πr
44/2π = r
r = about 7 cm
d = 2r
d = 2*7
= 14 cm
General equation: a = k*b^2
Specifically: 10 = k*(3)^2 = 9 k
Solving for k: k = 10/9
Then a = (10/9)b^2. If b = 9, then a = (10/9)(9)^2 = 90 (answer)
The side lengths are 16, 30, and 32
