Question

PLEASE HELP!!!!!!

Answer 1

surface area of cone+ surface area of hemisphere= entire surface area

Answer 2

\[SA = \pi r l + 2 \pi r^2\]

Answer 3

We will not include Surface Area of cone for circular part..

Answer 4

5.8π square inches ?

Answer 5

Let me check then..

Answer 6

\[SA = 3 \pi +1.125 \pi = 4.125 \pi\]

Answer 7

Agh! yeah it appears I did it two different ways and 4.125 and 5.1 were my two answers. _--lol thanks

Answer 8

Welcome..

Answer 9

surface area of cone= pi*r*sqrt (r^2+l^2) and surface area of hemisphere= 2*pi*r^2

Answer 10

yea agreed!!

Answer 11

it's cool :)
