oh, sorry .-. not Q24. I had to say Q20. how can we do it?

A )
X = 3
Y= 5
So Ratio 3:5

B) Ratio of Area is ^2 ratio of lengths

So (3 : 5)^2
9:25

C) The Volumes are ^3 of the ratio of Length

So (3:5)^3

27: 125

BTW, check it ....

***amd***, please post shear and strectch transformation!

no, for part C, its 27 : (5^3 - 3^3)
the only thing i dont get is, how can we deduce ratios of radii by just looking at slant heights?

I will explain the first one

In triangle SR1O
/_ SOR1 = 180 -100 = 80

/_SR1O = 40 (same triangle)

/_OSR1 = 180 - (80 + 40)
/_OSR1 = 60

/OSP1 = 180 - 60

Thanks

once i am done with at least 4 pprs today then i'll post it at night In shaa Allah

for c ..we cud write the ratio of X to Y as (Y/X)^-1
so it goes as(C-X/X)^-1
=(C/X -X/X)^-1
C/X =l^3 of C/l^3 of X) and X/X =1
u do the subsequent math

phhh..............just compared C with X by fault

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

because ratio of lengths are same

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

Thanks bro, but i dont only need the matrix thing................... I need to know whole of it I will do it by book!

Can anyone tell me how to do part d of the first Q? And the q in the second attachment??
Thanks in advance!!!
