Find The TOTAL SURFACE AREA Of The Composite Figure Shown PLEASE HELP ME OUT class=

Sagot :

Answer:

Lets find the cylinder's:

6 is the diameter so half of that is 3

3^2 = 9

9 x 3.14 = 28.26

28.26 x 2 = 56.52

Lets find the circumference then multiply by the height to get the round surface.

3 x 2 x 3.14 = 18.84 x 10 = 188.4

56.52 + 188.4 = 244.92 <--- surface area of cylinder

Now the surface area of the cube:

20 x 18 = 360

360 x 2 = 720

16 x 18 = 288

288 x 2 = 576

16 x 20 = 320

320 x 2 = 640

720 + 576 + 640 = 1,936 <------- surface area of the cube

Now lets add both surface areas!:

244.92 + 1,936 = 2,180.92 m2 is your answer.
