Answer 1

Since this is a composite figure, you need to divide the figure into at least two other shapes in which you know how to find the area of.

Answer 2

I know the area of each figure. Mathmale was helping me earlier

Answer 3

Now add the area together.

Answer 4

840

Answer 5

That will help you find the area in millimeters. And multiply by 10 to get the centimeters.

Answer 6

Oh wait hold on

Answer 7

Psh Okay its 300 xD

Answer 8

3000 when muliplied

Answer 9

Sorry you need to divide by ten to find the centimeters.

Answer 10

But you are incorrect.

Answer 11

Let's say that the bigger figure is Shape A and the smaller figure is Shape B. Shape A, you need to multiply 45*45 and in Shape B you need to multiply 30*30. What will you get when you add the two products?

Answer 12

61650

Answer 13

Are you sure?

Answer 14

Answer 16

2925

Answer 17

No problem and you're correct for finding the measurement in millimeters. NOW convert this in centimeters.

Answer 18

Nice work, both of you!

Questioner: Think: How many mm in 1 cm? You'll need this conversion factor.

Answer 19

I got 292.5 Cm But im not sure

Answer 20

1 mm = 0.1 Cm

Answer 21

I understand probably It is C.

Answer 22

Let's be careful always to use the proper units of measurement. Here's what I'd propose:

\[\frac{ 2925 mm ^{3} }{ 1 }*(\frac{ 1 cm }{ 10 mm })^{3}=?\]
