Edexcel GCSE Maths 9-1 - 2018 Paper 2

How did it go guys? For the Enlargement one I accidently added 1/3 of it's size onto it instead of decreasing it :frown:

.

But overall that was pretty good!

What did everyone get for the sphere question? I got 288pi (or 905 cm^2)
Also what about the angle between AH and the plane? I got 39.5 but i feel like I’m wrong
Also the last density question?

I got 0.43 as both rounded to this to 2 dp for the density Q

For the two you mentioned i got the same answers, for the final question on density i got 0.43 g/cm^3

I actually feel as if i got every single question which is nice.
EDIT: I for sure didn't i for sure dropped some marks HA^

You are wrong, question 9. is 2368.704

No they are right on that one. The first increase is 2.8 percent. 12000 x 1.028 = 12336. Then the second year is 1.4% increase which gives 12,508.704 but you round the pennies because you can't have .4 of a penny.
