What is the circumference of 6 cm?

12π cm
Finding the Circumference: If r = 6 cm, the the circumference is c = 2π(6) = 12π cm, if writing in terms of π. If you prefer a numerical value, the answer rounded to the nearest tenth is 37.7 cm.

How is the area of a circle calculated?

Area of a circle can be calculated by using the formulas:

1. Area = π × r2, where ‘r’ is the radius.
2. Area = (π/4) × d2, where ‘d’ is the diameter.
3. Area = C2/4π, where ‘C’ is the circumference.

What is the circumference of a 12 circle?

To find the circumference of a circle, you will use the formula C=2⋅π⋅r ; therefore the circumference C is 2⋅π⋅6≈38 inches.

How can we find area of a circle?

The area of a circle is pi times the radius squared (A = π r²). Learn how to use this formula to find the area of a circle when given the diameter.

How do you find the square cm of a circle?

Measure the diameter in centimeters. For this example, let the diameter measure 10 cm. Multiply the diameter’s length to itself to square it — 10 cm multiplied by 10 cm results in 100 cm^2. Multiply the squared diameter by pi — 100 cm^2 multiplied by pi equals approximately 314.2 cm^2.

What is the area and circumference of circle calculator?

Area = 201.1429 in² Area and circumference of circle calculator uses radius length of a circle, and calculates the perimeter and area of the circle. It is an online Geometry tool requires radius length of a circle. Using this calculator, we will understand methods of how to find the perimeter and area of a circle.

What is the diameter of a circle in meters?

A circle has a diameter of 2 meters. What is its circumference? If a circle has a area of 3.142 square meters. What is its perimeter?

What is the value of circumference c?

Circumference = π·d = 3.14·2 = 6.28(*) In terms of area: Circumference C = √ 4·π·A = √ 4·π·3.14 = 6.28(*) (*) 6.283 meters exactly or limited to de precision of this calculator (13 decimal places).

What is the distance from the center of a circle?

The distance from the center of a circle to any point on the circle is called the radius of this circle.A radius of a circle must be a positive real number. The circle with a center O O and a radius r r is denoted by c(O,r) c ( O, r).
