Pi refers to the circumference ratio to its diameter and is represented by the symbol Õ. The size of a circle is slightly three times larger than its diameter; that is why 3.142 is used as a constant. So when you ask, what is 20 times Pi, it means that you are looking for the Circumference of a circle whose diameter is 20. Therefore, 20 times pi is: 62.84.
Pi is also presented as 22/7 other times because it’s an irrational number. This means when you divide 22 by 7, you will get an infinite number of decimals (3. 14159265358). That’s why in most cases, you will find Pi represented by just 3.142
So 20 times Pi means 20 times 3.142 = 62.84
Therefore, 20 Times Pi is 62.84
How to Find the Circumference of a circle
Circumference refers to the perimeter of a circle.
The formula for finding Circumference is diameter times pi (Õ)
Let’s assume the diameter is 20
So the Circumference will be:
20 times 3.142 Which is 62.84
How to find the diameter given the Circumference of a circle
Since we know Circumference = Diameter X pi (Õ)
We can divide Circumference by Pi to find the diameter
The formula for finding a circle’s diameter is D = C / Õ
D –Diameter
C –Circumference
Õ – Pi
Assuming 20 is the Circumference the diameter of the circle will be
20 / 3.142, which is 6.365372374
How to find the radius(r) given the Circumference of a circle
Radius refers to a straight line from the center to the circle’s Circumference. It is half-diameter in size.
The formula for finding radius is: r = C/2Õ
r – Radius
C – Circumference
Õ – Pi
Assuming 20 is the Circumference. The radius of the circle will be
20 / 2 x 3.142, which is 3.182686187
How to find the area of a circle
The area of a given circle is the total area that the circle covers
The formula for finding a circle’s area is:
A = Õr²
A – Area
Õ – Pi
r – Radius
Assuming the radius of the circle is 20
The area of the circle will be
3.142 x 20²
Which is 1256.800
