Question

find area to the nearest square inch

Answer 1

Hmm i say you find the area of the cone then the area of the cylinder and then add them together...do you know the formulas for them?

Answer 2

yea

Answer 3

-_- please refresh my memory...

Answer 4

cylinder surface area = \[SA=2\pi rh+2\pi r^2\]
cone surface area =\[SA=\frac{ 1 }{ 2 } 2\pi r*l+r^2\]
l is slant

Answer 5

i think

Answer 6

Oh lets find the area of the cylinder first:
we have the formula
A = 2pirh + 2pir^2
So lets plug in what we have...
A = 2 x 3.14 x 6 x 15 + 2 x 3.14 x 6^2
A = 6.28 x 6 x 15 + 2 x 3.14 x 6^2
A = 37.68 x 15 + 2 x 3.14 x 6^2
A = 565.2 + 2 x 3.14 x 6^2
A = 565.2 + 6.28 x 6^2
A = 565.2 + 6.28 x 36
A = 565.2 + 226.08
A = 791.28

Answer 7

Ok...now that i look at what i just did i think we have the wrong formula...I think it is:
A = 2pir^2 + 2pirh

Answer 8

A = 2 x 3.14 x 6^2 + 2 x 3.14 x 6 x 15
A = 2 x 3.14 x 36
A = 6.28 x 36
A = 226.08
A = 2 x 3.14 x 6 x 15
A = 6.28 x 6 x 15
A = 37.68 x 15
A = 565.2
A = 565.2 + 226.08
A = 792

Answer 9

It wasn't that far off -_- ok my fault again...

Answer 10

im confused -_-
so i use the other formula?

Answer 11

The one that i listed? I believe so...
