There is a ring, the radius of the inner circle is 6cm, the radius of the outer circle is 10cm, what is the area of the outer circle

There is a ring, the radius of the inner circle is 6cm, the radius of the outer circle is 10cm, what is the area of the outer circle

Area s = 3.14 * (10 * 10-6 * 6) = 3.14 * 64 square cm = 200.96 square cm
