just tell me, in part (a), how can we deduce ratios of radii by just looking at slant heights?

The ratio of any corresponding sides in similar figures is a:b
The ratio of area of two similar figures is a^2 : b ^2

SO the volume of the clay is 500 cm^3

Radius of new depth is x+1.5 while it was x before it

So [(X+1.5)^2] X 6 ( hieght)] - [(X^2)x 6] = 500.............. Solve it for d

Does anybody have some notes for transformation?

thats what i know, bro.

Sir C has same base as Y has...

So Forget y, lets have C and X

X has 3 Slant Height while C has 5

Ratio 3:5....... It will countinue to be same for every length or hieght in this cones

-.- oh, fish!
I just realized these were similar figures

"Similar"
