We use it to calculate the circumference of a circle.
To calculate the area/circumference of a circle when designing something circular with a limited amount of material. i.e. you have to design a bronze circle and only have 27 sq ft of bronze. You have to calculate the circumference to see if you need to make the circle smaller or not.
It's the diameter times pi.
You get the largest area with a circle. Divide the perimeter by (2 x pi), then calculate the area with the formula pi x radius2.You get the largest area with a circle.

Divide the perimeter by (2 x pi), then calculate the area with the formula pi x radius2.
First you determine the radius of the circle. If 6.6 feet refers to the diameter, divide that by 2 to get the radius. Then you use the standard formula for the area of a circle.
the circle that divides the day from night is called circle of illumination
the circle that divides the day from night is called circle of illumination
yes
Well, once I looked up "circle of illumination" --(geology) The edge of the sunlit hemisphere, which forms a circular boundary separating the earth into a light half and a dark half. (circle-of-illumination) --I could just *begin* to understand your question, which is still very unclear. Please rephrase it. It just doesn't make sense.
The north or south most point of the insolations circle of illumination.
The north or south most point of the insolations circle of illumination.
The circle of illumination intersects the North Pole on the spring and autumnal equinoxes, March 20 or 21 and September 22 or 23, when the Earth's North and South Poles are not tilted toward or away from the sun, but are both at 90 degrees to the sun's rays. The sun is directly above the equator, and every location on Earth has 12 hours of daylight.
Pi can be used to calculate the area of a circle Pi can be used to calculate the circumference of a circle
At the moments when the sun is at the Summer and Winter Solstices ... on June 21 and December 21.
To calculate the area of a circle use this formula: pi x r2.
The radius of a circle is half of its diameter.
Radius of a circle = diameter/2
