Two cones formed from two circular sectors 2018-11-30
APARNA pose la question :
The central angles of two sector of a circle are 60° and 120° . Using these sectors two cones are made. If the radius of the smaller cone is 5 cm, find the radius and base area of the larger cone.

A circle is divided into three sectors 2014-04-17
atolagbe pose la question :
the area of a circle is 154cm square. it is divided into three sectors such that two of the sectors are equal in size and the third sector is three times the size of the other two put together. calculate the perimeter of the third sector. take pi=22/7?

Irrigation and a sector of a circle 2004-12-23
Chuck pose la question :
A friend of mine is a farmer and uses Pivots to irrigate portions of his land. The crop rows are in straight lines that all form chords of a large circle. The intent is to determine area between any two "boundary" rows expressed in acres.

Collinear Points 2003-01-13
Gary pose la question :

Which of the 4 points are collinear when you construct the following concurrent lines or rays of a triangle?

  1. P(1), the point where the angle bisectors intersect.
  2. P(2), the point where the altitudes (or extensions) intersect (inside or outside of the triangle).
  3. P(3), the point where the medians intersect.
  4. P(4), the point where the perpendicular bisectors (or extensions) of the three sides of a triangle intersect.

This is for my 9-12 high school class in geometry.
My name is Gary

Thanks for your help.

Applied geometry 2001-11-02
Jenny pose la question :
Where can I find some hands-on activities for my Applied Geometry classes? I want to do more activities with them that allow us to get out of the classroom. However, I want to use activities that use only inexpensive equipment because I usually buy the equipment myself.

Rebecca Henry pose la question :
Points A,B,C,D,E,F are equally spaced on a unit circle. Arc CGE has a center A. Find the number of square units of area in the shaded region.
Walter Whiteley lui répond.
Common Area of two sectors. 1996-11-06
Lynda Mow pose la question :
How do I find the area common to two intersecting circles of radii 8 ft and 10 ft if their common chord is 10 ft long?
Penny Nom lui répond.
