a). Pretty sure you round down did that type of maths just this year.
b). What do you mean by irrational?
I am very confused.
Any chance you could explain all this in simpler terms I havn't learnt like anything your saying and dont really understand it.
Hi im a yr 9 student and im needing some help.
Im wondering if a equilateral triangle is enclosed in a circle with 100m radius how to find out the area. So far i arrived at 14907.11985cm squared. How i did that was divide the triangle up into three iscosels triangles.
Then the angles of each where 30 degrees,30 degrees and 120 degrees. I then plussed the two equal sides which equaled 200 cm and times them by 120/180 to find the base of 133.33333333 recurring. i then used this site to find the area: http://www.ajdesigner.com/phptriangle/isosceles_triangle_area_k.php
this is based on all my dodgy guesswork so i was wondering if you could help me
