P = I ( 1 + y'^2 )^1/2 dx
Where: I - Integral (from point a to point b)
suppose the circle is x^2 +y^2 + a^2
the perimetr will be 4 times the perimeter in the first quadrant
now take a small element
ds on the curve
by Pythagoras theorm
ds2 = dx2 + dy2
now rearange
to get the formula on top
To find the area you multiply pi (3.14) by the radius and then multiply your answer by the radius again. For example:
Say the radius is 10cm. You would go 3.14x10x10.
IMPORTANT: 3.14xr2
is different than 3.14xrx2!
Also, if you have the circumference of the circle but need the radius, just divide the circumference by 2.
Hope this helps!

What is circumscribed area and inscribed area of regular polygon?
circumscribed means the polygon is drawn around a circle, and inscribed means the polygon is drawn inside the circle. See related links below for polygon circumscribed about a circle and polygon inscribed in a circle.
What is a circumscribed polygon?
A circumscribed polygon is a polygon all of whose vertices are on the circumference of a circle. The circle is called the circumscribing circle and the radius of the circle is the circumradius of the polygon.
How do you find perimeter of a polygon?
add the sides of the polygon.
How do you figure the perimeter of a polygon?
The perimeter of a polygon is the distance around the outside of the polygon. A polygon is 2-dimensional; however, perimeter is 1-dimensional and is measured in linear units.To find the perimeter of a polygon, take the sum of the length of each side.
How do you find the permeter of a polygon?
The perimeter of a polygon is the sum of the length of each of its sides. If the polygon is a regular polygon the you can calculate the perimeter as [number of sides] *[the length of one side]
The center of a regular polygon is the common center for the inscribed and circumscribed circles of the polygon?
Correct.
How do you find the perimeter of a regular polygon with the apothem and area?
Perimeter = 2*Area/Apothem.
Find the apothem of a regular polygon with an area of 625 m2 and a perimeter of 100 m?
Find the apothem of a regular polygon with an area of 625 m2 and a perimeter of 100 m.
A circle drawn around a polygon so that each vertex of the polygon lies on the circle?
Circumscribed.
How do you do perimeter problems?
To find the perimeter of any polygon, add up the lengths of all the sides.
What is the difference between inscribed and circumscribed?
== == Inscribed is a polygon inside a circle with all points on a given point in the circle. Circumscribed is a circle inside a polygon with any given point touching just one point on the polygon. Hope this helped.
What is meant by a circle being circumscribed about a polygon?
It means drawing a circle around a polygon in such that each vertex of the polygon is on the circumference of the circle.
