The circle has a radius of 3/4 inches.

I watched on Jeopardy that all the kids thought the Great Wall of China was bigger and I wanted to know so tutor away!

If the top surface of a particular slice of pie is a sector of a circle with a vertex angle measuring 20 degrees and the length of the arc is 3.14π units, what is the perimeter(left in terms of π)...

I am confused by this, and unable to understand this

I don't want it done using a formula. I want to learn how to do it using cos, tan, sin or sin(a)/A = sin(b)/B, sin(b)/B=sin(c)/C.

Its an area

The equation of a circle is x^2+y^2-2x+6y+3=0. What are the coordinates of the center and the length of the radius of the circle.

Detail of figure - draw a circle with centre o and diametre AB and chord CD parallel to it .through chord CD make an angle CED above centre O of the circle at any point on the circle .

So here is the explanation. Draw a circle with center O. Draw a line vertically upward from O to the circumference and mark it A. Draw a line from O vertically downward and mark the...

Complete the square and write the equation of the circle into standard form. 5x^2-9x+5y^2-8y=0 Find the center (h,k) and radius r.

a diameter of a circle has endpoints (2,3) and (4,5).

we know that the circumference of the circle is 2(pi)r so if we draw lines from each point to the centre then we should get the area of the circle and it should be 2*(pi)*r*r , ;) instead of (pi)*r*r...
