Does any one have notes on doing enlaregment and shear?
And I am not able to do this question. The paper is may/june 2013 Variant 41 question 9 part b, if any one can solve it and show it to me would be really helpful. thanks.

4)b)x=new height
find the scale factor=³√(volume of original piece of cheese / volume of similar piece of cheese)=³√(90/22.5)=³√4
3.84/x=³√4
3.84/³√4=x
x=2.42

no d
check that it is the variant you need help in

this is loci
so i'll just tell u how to do it
(a)perpendicular bisector (stand on G by the compus and open it more than the half of the length GH
draw 2 arcs before the line GH and after
do the same when on H but don't change the length opened by the compus
there should be 2 intersections around the line GH join them together to draw the perpendicular bisector )

(b)angle bisector (draw 2 arcs on lines GH and GF when standing on G
Then with the same length stand on the intersection between the arc and the line and draw another arc between the 2 lines repeat it on the other line
draw a line to join the intersection of both arcs drawn in last step and point G)

(c)change 550 to cm
550/100=5.5
open the compus to 5.5 cm then stand on f and draw a circle

R should be nearer to G and line FG and out of the circle
after you answer it send a pic if u r not sure it is right

Thankyou! i'm going to try this again
