Answer 1

D=6units

r= 3units

circumference /perimeter =2πr

i.e, 2x22/7x3

so the answer is 18.85 units.

hope it will help you...

Answer 2

Answer:

diameter= 6 units

then radius is= 3units

$circumference \: of \: circle = 2\pi \: r \\ so \: circumference = 2 \times \frac{22}{7} \times 3 \\ = > 18.9 \: units$
