What is the area of a circle with a radius of 2 cm? In Euclidean
geometry, that a circle is the set of all points on the field in a certain
distance, called the RADIUS, from a certain point, called the Center. The
circle is an example of a simple closed curve which divides the field into the
inside and the outside.
The formula to find the broad
circle is as follows.
area = π x r2
The formula for finding the
circumference of a circle is as follows.
C = 2 x π x r
or
π x D
Description:
r
= radius
D
= diameter
π
= phi, 22/7 or 3.14
If the radius is a
multiple of 7 like 7, 14, 21 and then use phi = 22/7
If the radius is not
a multiple of 7 as 5, 10, 12 and use phi = 3.14
What is the area of a circle with a radius of 2 cm?
area = π x r2
area = 3.14 x 22
area = 3.14 x 4
area = 12.56
So,
area of a circle with a radius of 2 cm is 12.56 cm2.
