For the actual solution, tbh, you only need to show: 1) ADK congruent to AEK => DK = DE 2) DKB congruent to DFB => DK = DF => DE = DF 3) DE = DF, DC = DC, angle DFC = angle DEC = 90° => DFC congruent to DEC [RHS congruency] Hence, angle DCF = DCE => DC is angle bisector of ACB therefore, angle bisectors of a triangle are concurrent

anyone know how to factorise 4k^2 + 16k + 3. I am trying to solve by using splitting the middle term but am not familiar with it. if some one could teach this method it will help a lot (ps ik how to use quadratic equation, just seeking to find a simpler solution)

On Archimedes' tombstone there is said to have been an inscription sol showed a cylinder with an inscribed sphere. 2500 years ago Archimedes found that the ratio between the globe volume and the cylinder volume was always 2/3.

B) it is actually the case that even the sphere area is 2/3 of the area of ​​the cylinder. Show that it is so. Tip: put the measurement on the globe and the cylinder and count your measurements

Basically, it's a principle as follows: Suppose two 3d-objects are included between two parallel planes. If the cross-section of two objects on a plane is equal in area, the two objects have the same area.

The standard way to do it is to compare a hemisphere of radius r and a cylinder of radius r and height r minus an upside-down cone with the same radius and height.

Well, that's not usually taught in schools, because that technique was rendered obsolete with calculus. But if you want to solve it the was Archimedes did, you have to use that principle.
