Answer:
about 572.6 square centimeters
Step-by-step explanation:
There are 3 circles outside the center one, so the total radius is 3·4 cm = 12 cm more than the radius of the inner circle.
The inner circle has a diameter of 3 cm, so its radius is 1.5 cm. That means the radius of the entire target is 1.5+12 = 13.5 cm.
The area of a circle is given by the formula
A = πr^2
For a radius of 13.5 cm, the area is ...
A = π(13.5 cm)^2 = 182.25π cm^2 ≈ 572.6 cm^2
