Question

@angle I need help

Answer 1

number 3

Answer 2

@AZ

Answer 3

All of them?

The first one is a rectangular prism

SA formula for a rectangular prism = 2(LW + WH + LH)

we have sides of 2, 3, and 5 so

SA = 2*(2*3 + 2*5 + 3*5)

SA = ??

Answer 4

idk

Answer 5

Just simply put it in the calculator and you'll get your answer.

Answer 6

what is 2 * 3 =

what is 2 * 5 =

what is 3 * 5 =

Answer 7

2*3 is 6 2*5 is 10 3*5 is 15

Answer 8

good so now we have

SA = 2*(2*3 + 2*5 + 3*5)

SA = 2 * (6 + 10 + 15)

what is 6 + 10 + 15 =

Answer 9

31

Answer 10

@az

Answer 11

Good so now we have

SA = 2 * 31

SA = ??

62

Answer 13

so that's your SA for the first question

Answer 14

For the second one,

SA = bh + L(s1 + s2 + s3)

our b = 6
h = 4

L = 10
s1 = 6
s2 = 5
s3 = 5

so plug it in

SA = (6*4) + 10*(6+5+5)

so first, what is 6 + 5 + 5 =

Answer 15

I need number 4

Answer 16

Surface area of a cylinder = \( 2 \pi r h + 2 \pi r^2\)

r = 8
and h = 9

so what is

SA = (2 * 3.14 * 8 * 9) + (2 * 3.14 * 8 * 8)

SA = ?

Answer 17

idk

Answer 18

okay, what is

2 * 3.14 * 8 * 9 =

Answer 19

72

Answer 20

no

8 * 9 = 72

but what about

2 * 3.14 * 8 * 9 =

Answer 21

452.16

Answer 22

Good and what is

2 * 3.14 * 8^2

or 2 * 3.14 * 8 * 8 =

Answer 23

401.92

Answer 24

Good so now we went from
SA = (2 * 3.14 * 8 * 9) + (2 * 3.14 * 8 * 8)

to
SA = 452.16 + 401.92

sA = ??

Answer 25

854.08

Answer 26

That's your surface area of the cylinder

Answer 27

close it he good damn

Answer 28

close the question
