crispy snow dipped can you help?

crispyrat:

sure im not rlly good with three dimensonal but lets do this ok so what is the radius of the cone?

xXQuintonXx:

2.5

xXQuintonXx:

wouldnt it be the same formula as wut i just did but 2.5^2, then i add them together

crispyrat:

yes i believe so it would be the same formula but u divide by 3 xp

crispyrat:

oh wait a sec the radius i 3 cus we are using the bottom circle not the height! so same thing but divide by 3

view this first

xXQuintonXx:

ya lost me

crispyrat:

the full thing would be (3(pi)*3(radius)^2*5(height))/3

xXQuintonXx:

45

xXQuintonXx:

so 45+378=423

crispyrat:

yesyes i believe so very good

xXQuintonXx:

so 423 is my answer?

crispyrat:

yes :)

xXQuintonXx:

yes it was correct thank you :)
