What is 80 times Pi?

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 80 times Pi, it means that you are looking for the Circumference of a circle whose diameter is 80. Therefore, 80 times pi is: 251.36.

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 80 times Pi means 80  times 3.142 = 251.36

Therefore, 80 Times Pi is 251.36

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 80

So the Circumference will be:

80 times 3.142 Which is 251.36

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 80 is the Circumference the diameter of the circle will be

80 / 3.142, which is 25.4614895

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 80  is the Circumference. The radius of the circle will be

80 / 2 x 3.142, which is 12.73074475

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 = Õ

A – Area

Õ – Pi

r – Radius

Assuming the radius of the circle is 80

The area of the circle will be

3.142 x 80²

Which is 20108.800
