Question

2. Mendel’s team built a structure for a competition using wooden spheres and cylinders. The wood they used weighs 1 g for each 1.4 cm3. They used 4 spheres and 4 cylinders to build the base of the structure. Each sphere has a radius of 4.45 cm. Each cylinder has a radius of 3 cm. The base weighs 1700 g. What is the height of the cylinders? Use 3.14 to approximate pi and round the answer to the nearest whole number. Show your work.

Answer 1

ok, lets see here

Answer 2

haha, this one is a bit tougher

Answer 3

Oh no :"""(

Answer 4

it will take around 2 - 5 minutes

Answer 5

Okaiii

Answer 10

oohhhh, nvm the question is different than what my thought process was going off of
let me rethink this

Answer 13

here is my work

Answer 14

ill draw it this time :P

Answer 15

Okay

Answer 16

oh, wait that answer is wrong

now ill show my work

Answer 20

Okai

Answer 21

ok :P i need to rework it

Answer 22

Okaii no rush

Answer 23

ok, i took 4.45*3.14*2*4 = 111.784/1.4 = 79.845714285714285714285714285714
1700 - 79.845714285714285714285714285714 = 1620.1542857142857142857142857143
1620.1542857142857142857142857143 / 3 / 4 = 135.01285714285714285714285714286 that should be rounded to 135 as a whole number for the height of the cylinders, can you tell me were i messed up? i know i messed up somewhere, but its too early in the morning for me to do math properly XD

Answer 24

i had a red bull late last night, but its wearing off

Answer 25

Ehhhhhhhhhhhhhhh I dunno o.o XD

Answer 34

phew, i hope you are satisfied ^_^ that is the answer and how i got it
