✔ 最佳答案
area = πr², where r is the radius

d = diameter
r = radius
r = d/2
A = π r ² units ²
2008-04-06 12:57 am
area=r^2pi
2008-04-06 12:49 am
a = πr^2
(a = area , π = pi , r = radius)

area of a circle = pi(3.14) x (radius x radius)

use this formula pie r 2
pie r sqaure.
the value of pie is 22/7 or 3.14 and r is the radius of circle
2008-04-06 12:46 am
πr2
2008-04-06 12:46 am
pi r squared
2008-04-06 12:43 am
area = pi* r^2
