A circle with radius of 2cm sits inside a circle with radius of

Answer 1

Answer:

37.70 cm^2

Step-by-step explanation:

area of circle with radius 4 cm = (pi)r^2 = 3.14159 * (4 cm)^2 = 50.27 cm^2

area of circle with radius 2 cm = (pi)r^2 = 3.14159 * (2 cm)^2 = 12.57 cm^2

difference in areas = 37.70 cm^2
