Answer 1

The picture below shows a container that Tim uses to freeze water:

What is the minimum number of identical containers that Tim would need to make 2000 cm3 of ice? (Use π = 3.14.)

5

7

22

20 <---
i originally got 19.90445.... but i rounded

Answer 2

How did you get that ?

Answer 3

the 20 or 19.90445...?

Answer 4

19.90445

Answer 5

ok well i used the volume formula so it was v = pir^2h

Answer 6

you are correct it is 19090445 but you do round it to 20

Answer 7

19.90445

Answer 8

then ?

Answer 9

and the diameter is 4 and i know radius is half of a diameter so i did
v = 3.14 x 2^2 x 8 i did 3.14 as pi because they said so and 8 is the height giving then i got
100.48 and devided that by 2000 so 2000/100.48 = 19.90445...

Answer 10

and i rounded the 19.90445.. to 20

Answer 11

find the volume of 1 container

V=πr2h


in the diagram the radius is 2cm as the diagram shows a diamter
height = 8 cm


calculate the volume

V=π×22×8
which equals the 19.90445 then u round

Answer 12

how did you get radius as 22?

Answer 13

typo 2^2

Answer 14

yeah i did the same thing as you then

Answer 15

yeah so ur right

Answer 16

no hold on

Answer 17

You are right. Round it to 20

Answer 18

you said this "V=π×22×8
which equals the 19.90445 then u round"

but pi x r^2 x 8 doesn't equal 19.90445 it equals 100.48

Answer 19

okay thanks i got more if you can help me?
