Step-by-step explanation:
The area of a circle is:
π (Pi) times the Radius squared:
A = π r2
or, when you know the Diameter:
A = (π/4) × D2
or, when you know the Circumference:
A = C2 / 4π
Step-by-step explanation:
a=12
d=6-12=-6
Tn=a+(n-1)d
Tn=12+(n-1)×-6
Tn=12+(-6)(n-1)
Try this formula(n-2)180/n (n is number of sides)
