What is the ratio of the radius of a circle to its perimeter take π 22 7?

where ‘r’ is the radius of the circle and π is the mathematical constant whose value is approximated to 3.14 or 22/7. The circumference of a circle can be used to find the area of that circle….Circle and Parts of a Circle.

What is the area of the circumference is 16?

Explanation: The area of a circle is πr2 where r is the radius. Dividing both sides by π we find r2=16=42 and hence r=4 .

What is the circumference of 16 cm?

16π≈50.27 in.

What is the radius of a 16 circle?

If the 16 cm is the diameter then the radius is 8 cm.

What is the radius of 16 cm?

What is the diameter of a 16 cm circle?

How to calculate the perimeter of a circle from its radius?

Generally, you want to calculate the perimeter of a circle from its radius. That’s why we offer you this tool. However, if you have the diameter, you simply divide this by 2 to get its radius: Thus, you can calculate the perimeter of your circle from its radius or diameter.

What is the area of a circle with diameter 11 cm?

Perimeter = 25.13 Let us reproduce the example with a circle with a diameter of 11 cm: Perimeter = 34.56 Note that all dimensions are expressed in the same unit (in this example in centimeters). Also discover our calculator to get the area of a circle.

What is the formula for the shape of the perimeter?

Formula Name of the Shape Perimeter Formula Circle 2πr Triangle a+b+c, where a,b and c are the sides of Square 4a, where a is the length of side of squ Rectangle 2 (L+B), where L is length and B is brea

How to calculate the perimeter of a sector using a calculator?

First, the calculator calculates h = (major radius – minor radius) 2 / (major radius + minor radius) 2. Then it computes the perimeter as equal to π x (major radius + minor radius) x (1 + h * 0.25 + h2 * (1/64) + h3 * (1/256) + h4 * (25/16384) + h5 * (49/65536) + h6 * (441/1048576). Visual on the figure below: Perimeter of a sector
