How to find perimeter of a circle with radius?

A circle is a special type of a geometric figure. Its perimeter is the sum of all line segments that are drawn around it. The perimeter of a circle with radius equals to πr. So, to find the perimeter of a circle, you need to input the value of radius and π.

How to find the perimeter of a circle with radius and diameter?

If you want to find the perimeter of a circle with diameter and radius you need to calculate the area of the circle. You can do it using the well-known formula A = pi*r*r. Dividing the given sum by two will give you the circumference of the circle. Alternatively, you can use the Pythagorean Theorem which is A = sqrt((r)*(r) + (diameter)). The perimeter of the circle equals to the sum of the three sides

How to find perimeter of a circle with diameter?

To find the perimeter of a circle with diameter, use the Pythagorean Theorem. The Pythagorean Theorem states that the sum of the squares of the two sides of a right triangle is equal to the square of the hypotenuse. If you put the diameter of the circle into this equation, you will get the length of the perimeter:

How to find the perimeter of a circle with radius?

One of the most common ways to measure the perimeter of a circle is to use the Pythagorean Theorem. To do this, you take the length of each side of a right triangle and add them together to get the perimeter. You can use this method with any triangle, but a circle is a great place to start. If you know the radius of the circle, you can use the Pythagorean Theodem to find the perimeter.

How to find the perimeter of a circle with diameter?

If you know the diameter of a circle, the perimeter is just twice the diameter. So, if you have the diameter of a circle, you can find the perimeter in the form of the algebraic equation 2 × diameter. However, you can also find the perimeter of a circle with diameter using the radius. If you have the radius of a circle, you can find the perimeter using the equation 2 × π × radius.
