Sagot :
Area or a circle
A= 3.14 (pi) multiplied by the radius to the second power
So if a circles radius is 3 cm it would be pi multiplied by 9 which equals 28.27 cm2
Circumference
C= pi multiplied by the diameter
A= 3.14 (pi) multiplied by the radius to the second power
So if a circles radius is 3 cm it would be pi multiplied by 9 which equals 28.27 cm2
Circumference
C= pi multiplied by the diameter
To find the corcumference of the circle the formula is 2(pi)r
to find the area of the circle the formula is (pi)(r)(r)
to find the area of the circle the formula is (pi)(r)(r)
