Answer:
Area A = 72.25[tex]$ \pi $[/tex] sq. units
Circumference C = 17[tex]$ \pi $[/tex]
Step-by-step explanation:
The diameter, d of the circle is given to be 17mm.
Since, 2r = d, where r is the radius r = [tex]$ \frac{17}{2} $[/tex] mm.
Area A of the circle is given by [tex]$ \pi r^2 $[/tex] sq. units.
Therefore, A = [tex]$ \pi \times (\frac{17}{2}) ^2 $[/tex]= 72.25 sq.mm.
Also, Circumference, C = [tex]$ 2 \pi r $[/tex] units.
Therefore, C = [tex]$ 2 \times \pi \times \frac{17}{2} $[/tex] = 17[tex]$ \pi $[/tex] units.
