Answer:
22.2 cm
Step-by-step explanation:
First, find the area of the larger circle.
50.2 x 2.5 = 125.5
Now, we need to find the diameter of the larger circle. We have the area, so we can plug this value into the formula of the area of the circle to find the diameter.
A = pi • r^2
125.5 =3.14 •r^2
122.36 = r^2
r = 11.1
Since radius is half the diameter, multiply r by 2.
11.1 x 2 = 22.2 centimeters
