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)...

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

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.

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 .

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.

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...

The equation of circle O in (x-5)^2+(y+1)^2=65. Does circle Oncontain the point (-2,3)?

4) Another Ferris wheel has a radius of 25 feet and reaches a maximum height of 55 feet above the ground. From the location of your seat when the wheel starts turning, it takes you 6 seconds...

A circle with centre O .draw two chords AC and BC joining both ends of two chords to centre O .now join A to B then draw also JOIN OC which intersect AB at M .

x^2+y^2+6x-10y-10=0

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...

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.

AB and CD are two chords of a circle intersecting each other at point E. Prove that AEC = 1 2 (Angle subtended by arc CXA at centre + angle subtended by arc DYB at the centre). Answer...
