What is the measurement of base?
The answer will depend on what measure is required: length of a side, perimeter, radius or diameter (if circular), eccentricity (if an ellipse), area.The answer will depend on what measure is required: length of a side, perimeter, radius or diameter (if circular), eccentricity (if an ellipse), area.The answer will depend on what measure is required: length of a side, perimeter, radius or diameter (if circular), eccentricity (if an ellipse), area.The answer will depend on what measure is required: length of a side, perimeter, radius or diameter (if circular), eccentricity (if an ellipse), area.
Regular octagon with apothem of 12?
Placing a question mark at the end of a phrase does not make it a sensible question. Try to use a whole sentence to describe what it is that you want answered.Yes, such an octagon can exist but it is not clear whether you want the lengths of its sides, its perimeter, or its area, or the radius of the circumcircle!
What is the perimeter of a regular octagon?
If you know a side length, s, the perimeter is 8 sIf you know the circum radius, r, (the distance from the center to a vertex) , the perimeter isp = 8 r sqrt(2 - sqrt(2)) (approx 6.12 r)If you know the apothem, a, (the distance from the center to the middle of a side),p = 16 a sqrt(2-sqrt(2))/sqrt(sqrt(2)+2) (approx 6.63 a)
How do you draw the radius of a circle?
A line of any length may act as the radius of a circle. The radius is the distance from the centre to the perimeter of a circle.
How do you find the radius of a circle if you know the perimeter?
you can divide the perimeter(circumference) by pi(3.14) and then once you get your answer you divide that by two giving you the length of the radius of the circle. ex: perimeter = 34pi 34pi/pi 34/2=diameter 16=radius
Find the length of the radius of a regular quadrilateral with a perimeter of 16 cm?
A "regular quadrilateral" is a square. The word "radius" isn't used for squares (or polygons in general). To get the length of a side, divide the perimeter by 4. To get the diagonal of a square, multiply the length of a side by the square root of 2.
What is the area of an octagon with a radius of 8?
Radii are related to circles.What do you mean by an "...octagon with a radius..."?Unless the octagon is regular it is impossible to to calculate the area of the octagon from one measurement alone.So assuming that the octagon is a regular octagon, what do you mean by radius? Do you mean:the radius of the circumcircle which passes through all verticesarea regular octagon = 8 × ½ × 8 × 8 × sin(360°/8) units² = 256 × sin(45) units²= 256 × 1/√2 units²= 128√2 units²≈ 181 units²the radius of the inscribed circle, which is the apothem of the octagonarea regular octagon = 8 × 8 × 8 × tan((360°/8)/2) units² ≈ 196 units²Something elseRe-ask your question explaining what you mean by "radius".

Determine the perimeter of a rectangle?
The formula for perimeter varies based on what object you are trying to determine the perimeter for. If you are looking for the perimeter of a perfect square you simply take the length of one side and multiply it by four. If you are looking for the perimeter of a rectangle with length (a) and width (b) you would multiple the length (a) by two and the width (b) by two and add them together. Perimeter = 2a + 2b If you are looking for the perimeter of a rectangle you add up the lengths of all the sides. To find the perimeter of a circle you multiple the radius by 2pi. pi = 3.14159265 the perimeter = 2 * 3.14159265 * r Or if you have the diameter of the circle you would just have to multiply the diameter by pi. So, perimeter = 3.14159265 * d Radius is the length of a line that goes from the middle of a circle to the edge of the circle. Diameter is the length of a line that goes from one edge of a through the middle to another edge of the circle.

A radius of a regular triangle is 12 Find the length of one side of the triangle?
A radius of a regular triangle is 12 . find the length of one side of the triangle?
What is the area of a regular polygon if the radius is 8 cm?
The area of a regular polygon with n sides is the half of the product of its perimeter and the apothem. So that you do not have enough information to find the area of the polygon (for example how many sides it has, or the side length).
What is the radius of the circle equal to?
Radius of a circle= Perimeter of the circle/2*pi Radius is half the diameter Radius is the length of a straight line from the center point of the circle to the edge of the circle.
