**What is the area of a circle with a radius of 1 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 r**

^{2}

*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 1 cm?**

area = π x r

^{2}
area = 3.14 x 1

^{2}
area = 3.14 x 1

area = 3.14

*So, area of a circle with a radius of 1 cm is 3.14 cm*

^{2}.**What is the area of a circle with a radius of 1 cm?**

**3.14 cm**

^{2}
What is the area of a circle with a radius of 1 cm? This is the answer
