What are the coordinates of the point of intersection of the angle -225 and the unit circle?
[-sqrt(2), -sqrt(2)]
How many diameters in a circle?
The diameter is just the width of a circle. If you drew a straight line threw a 2D circle all the way across that would be it. If you Multiply the radius by 2 then you will get the Diameter. Or, if you know the area of the circle you divide the area by pi (3.14).
How do you divide a circle into 8 equal parts using 3 lines?
Draw two diameters perpendicular to each other. Draw a smaller circle with the same centre such that the radius of the inner circle is 'r' and the radius of the outer circle is 'r√2.' [Or, the radius of the outer circle is R and the radius of the inner circle is R/√2.]
When 2 sides meet what is the point called?
Intersection point in lines & in figures' sides it's called vertex.
What is the curve between 2 points in a circle called?
If the curve is part of the circumference of the circle, it is called an arc.
What are the coordinates of the point of intersection of the angle -225 and the unit circle?
[-sqrt(2), -sqrt(2)]
How can you change 6.5 diameters to square centimeters?
if the diameter of the circle is 6.5 cms,then the area of the circle is ((6.5 / 2)^2) * 3.14159 = 33.183 sq. cms..calculation for circle area is:.radius squared * pi (a constant 3.14159)

The diameter of one circle is 2 feet longer than the diameter of another circle together the diameters equal 20 feethow long is each diameter r?
10 ft
What 2 dimensional shape has the most lines of symmetry?
A circle or annulus. Each of its infinite number of diameters is an axis of symmetry. Plus there is the line through its centre and perpendicular to the plane of the circle.
What is the intersection of 2 lines called?
the coulor green

How many diameter and radius are there in a circle?
If you are talking about around the circle (Circumference) then the are about 3.14 diameters and 6.28 radii While if you are talking about just across, the 1 diameter and 2 radii. Hope this Helps ;) Please recommend me :)
What is a cynosure of Pi?
A circle with a diameter of 2 is the guiding cynosure when Pi is the square of all possible circles: If the square root of Pi defines the side of a square and that square can be inscribed within a circle or enclose a circle, then the diameters of all possible circles between the largest and smallest include the circle of which Pi is its perfect square (a diameter of 2).
What is a Pi in Algebra's 2?
Pie is 3.14 etc etc etc. Its used in all the formulas to calculate the sums of a circle. Including Diameters, Radiuses and arcs & etc.
Can 2 circle and 3 lines get 17 intersection points?
Yes. Draw three line segments so that they cross at three points forming a triangle (with each side extending beyond the vertices of the triangle). Draw one circle to enclose the triangle without touching it to intersect the extended sides at a further 6 points, making 9 points of intersection so far. Draw the second circle slightly shifted (relative to the first) so that it also encloses the triangle (without touching it) creating a further 6 intersection points with the three lines and 2 with the first circle; an additional 8 intersection points making 17 in all.
How do you find the radius if the great circle is 706.5?
The great circle is simply the intersection of a sphere with a plane through its centre. It is, therefore, equivalent to the circumference.Then r = C/(2*pi) = 112.4 units.
