Square metres.
This diagram shows a target made
from four concentric circles (circles
with the same centre). The radius
of the inner circle is 2 cm. The
radius of the other circles increases
by 2 cm each time.
Calculate the area of each of the
rings numbered 1, 2 and 3. Give
your answers to a suitable degree
of accuracy.
