Question

A ball of diameter 20 cm fits exactly inside a cylindrical container, as shown below

The maximum volume of liquid which can be poured into the cylindrical container when empty is ________ cm3.

[π=3.14]

Answer 1

hint:

The diameter and length of the cylinder is the same

Answer 2

and these both ^^ are equal to diameter of ball

Answer 3

that's too much of a hint already

Answer 4

so im looking for the volume
V=pi.*5^2 *10 is tht right? and you get 758.4

Answer 5

first, write down the volume formula of a cylinder

Answer 6

V = 22/7r^2h

Answer 7

785.7 i thnk is the answer

Answer 8

\[v=\pi r^{2}h\]

Answer 9

thts wat i put . i use 22/7 as Pi

Answer 10

plug the values in

Answer 11

v = 22/7 * 5^2 * 10
v = 22/7 * 25 * 10
V=3.142857142837143 * 25 * 10
v = 78.5 rounded is 78.6 * 10
v= 786

Answer 12

does it look like this?
\[v=(3.14)(10)^{2}(20)\]

Answer 13

where did you get the 25?

Answer 14

nooooo bc i put 5 but ts wrong bc yu say 10 so let me redo it

Answer 15

\[r=\frac{ d }{ 2 }\]

Answer 16

i got 6280

Answer 17

is that answer one of the choices or something quite near the value?

Answer 18

well it isnt multiple choice

Answer 19

k. assuming that the pi value is 3.14 then you're right on the ball

Answer 21

thank you so very much . i have 2 more questions. to go then im done .

Answer 22

look at that link to see what other information you can learn about radius and diameter

Answer 23

thank you
