Question

Two similar solid have a scale factor of 3:5.If the height of solid I is 3cm, find the height of solid II
If the surface area of I is 54pi. cm^2,find the surface area of II
If the volume of II is 250pi. cm^3,find the volume of I
If the ratio of the volumes of two similar solids is 8:125, then what is the ratio of their surface areas

Answer 1

@jhonyy9

Answer 2

@jhonyy9 does this help??

Answer 3

so there is a scale factoe of 3,5

i think this will help you understanding and how you need to calculi the needed

ok ?

Answer 4

factor

Answer 5

so this mean that if the samler has a height of 1 than the second has a height of 3,5 *1

ok ?

Answer 6

one second example

so if the smaler has a side of 2 so the second will have a side with 3,5 time greater,longer so than what will be 3,5*2 =7

hope that this will make you understanding

Answer 7

so the height is 7

Answer 8

???

Answer 9

no

this was an example

Answer 10

you need calculi it

Answer 11

so would I tbe 5*3=15=hight of solid II

Answer 12

so if the height of sol. 1 = 3 than the height of sol. 2 will be 3*the factor scalar

Answer 13

9/15?? lik this

Answer 14

no

how many is 3*3,5= ?

Answer 15

I don't understand what you mean do I take 3*3=9 and 3*5=15??

Answer 16

no

how many is 3*35=?

Answer 17

1155

Answer 18

no

sorry you need learning multiplie

3*3,5
-----
5*3=15
3*3=9
------------- assum term by term ,down to 5 is nothing,zero so than willbe assumedby 0
105

but there not is 3*35 there is 3*3,5 so this mean that will be not 105 because there is a decimal virgule

than will be right 10,5

ok ?

Answer 19

sorry i need to go but i will be later

but hope so much that these my examples will help you solving this exercise sure easy right

Answer 20

ok I shude be an all day and nighth so whenever works thatnks so far If I have questions ill ask

Answer 21

ok

bye
