What is the area of a circle with a radius of 7 cm? This is the answer

What is the area of a circle with a radius of 7 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
C = 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 7 cm?
area = π x r2
area = 22/7 x 72
area = 22/7 x 7 x 7
area = 22 x 7
area = 154
So, area of a circle with a radius of 7 cm is 154 cm2.
