The circumference is the length all the way around the outside of the circle. … What is a circumference? Circumference is the distance around the perimeter of a circle. It is calculated by multiplying the distance across the center (diameter) by Pi (3.1416).
Also, How long is the diameter of the circle?
The diameter is the length of the line through the center that touches two points on the edge of the circle.

What estimate is closest to the circumference of a circle with a radius of 10 cm?
2π10=20π cm or about 62.8 cm.
What is the circumference of a circle of diameter 14 cm?
Diameter = 14cm. So radius = 14/2 cm = 7cm. Circumference = 2 pi r. So, circumference = 2 × 7 × 22/7 = 44cm.

s is the length of the side of the square. 
Rectangle  P=2L+2W  L and W are the lengths of the rectangle’s sides (length and width). 
Triangle  a+b+c  a,b , and c are the side lengths. 
What is area formula?
Given a rectangle with length l and width w, the formula for the area is: A = lw (rectangle). That is, the area of the rectangle is the length multiplied by the width. As a special case, as l = w in the case of a square, the area of a square with side length s is given by the formula: A = s^{2} (square).
WHAT IS lens formula?
Lens equation or lens formula is an equation that relates the focal length, image distance, and object distance for a spherical mirror. It is given as, Lens Formula – 1/u + 1/v = 1/f. where.
Is circumference a straight line?
Circumference: The circumference of a circle is the distance around it. Diameter: Any straight line that passes through the centre of the circle to two points on the perimeter. Radius: Any straight line that originates at the centre of a circle and ends at the perimeter.
How do you figure out a diameter?
If you are given the area of a circle, the diameter is equal to the square root of four times the area divided by pi (diameter = √ (4 x area) / pi).
How do u find the diameter of a line?
Divide the circumference by pi, approximately 3.14, to calculate the diameter of the circle. For example, if the circumference equals 56.52 inches, divide 56.52 by 3.14 to get a diameter of 18 inches. Multiply the radius by 2 to find the diameter.
