Question

circular cone help!!!
radius is 2
L.A- 12
whats the volume and the height????

Answer 1

if i knew i would help you. you r amazig!!

Answer 2

lol thank you lol

Answer 3

What does L.A mean?

Answer 4

lateral area dear:)

Answer 5

apply pythagoras theorem to find height
then the volume= 1/3 * base area*height

Answer 6

LA=12=2(pi)(r)(l) => from here you get l
now l= ((h^2)+(r^2)))^(1/2) => from here you get h
now volume = (pi)(r^2)(h)/3
hope this helps..

Answer 7

lateral area? lol, then i am wrong..

Answer 8

i got h=
4\[\sqrt{8}\]

Answer 9

is this right?

Answer 10

You won't have a rational number as your answer.

Answer 11

@shubhamsrg , ur formula of latent area is wrong

Answer 12

oh am sorry,,"2" wont be there..its pi(r)(l)

Answer 13

since LA=pi.r.slant.h=12
since r=2
so: slant.h=12/2pi=1.9
so the TA=4.pi.r(slant.h+r)=8pi(1.9+2)=98.01
so the Volume=T.A . H
but i can't find H

Answer 14

lateral area = pi*(diameter)*(slant height)
