A circle has radius = 19. Calculate Area, Circumference, Radius, Diameter
A circle has an area of 19. Calculate the radius, diameter, and circumference.Calculate radius (r):
A = πr2
Rearranging the equation, we get:
r = 2.Calculate diameter (d):
d = 2r
d = 2 * 2.
d = 4.9Calculate circumference (C):
C = 2πr
C = 2π * 2.
C = 4.9185π
