Question

1. Calculate the volume of the cone shown.
2. Calculate the surface area of the cone shown.
PLEASE HELP

Answer 1

V=1/3 pi r^2*h=1/3*pi*25*12=100pi
A=pi*r*a=5*13*pi=65pi

Answer 2

(A=surface area not the surface of all cone)

Answer 3

thanx ALOT!

Answer 4

uw

Answer 5

2)\[T=\pi rl+\pi r^2\]\[T=(\pi * 5*13)+(\pi *13^2)\]\[T=65\pi + 169\pi\]\[T=234\pi =735.1326809\]

Answer 6

wht's T?

Answer 7

T=surface area

Answer 8

A= 65 pi
surface area =234pi

Answer 9

ajajjajaj...i think i've calculated smth else....i have mistaken it 4 smth else..ur right sorry :$:$
