Diameter is 18

radius is half of diameter so 9

area is radius*pi ^2 which is 88.83

circumference is diameter * pi so 18*pi = 56.55

Answer:

$28 . 26cm$

Step-by-step explanation:

First find the radius

$d = 2r \\ 9 = 2r \\ \frac{9}{2} = \frac{2r}{2} \\ r = 4.5$

Now find the CIRCUMFERENCE

$c = 2\pi \: r \\ = 2 \times \pi \times 4.5 \\ = 9 \times \pi \\ = 28.26$
