V=pi*r^2*h
V=pi*100*100*40 cm^3
$${\mathtt{\pi}}{\mathtt{\,\times\,}}{\mathtt{10\,000}}{\mathtt{\,\times\,}}{\mathtt{40}} = {\mathtt{1\,256\,637.061\: \!435\: \!917\: \!295\: \!385\: \!1}}$$
1 256 637 cm^3
= 1256 637 mL
= 1 257 L (to the nearest L)
that would depend on what the units are to start with!
In a sence, whole numbers ARE decimal numbers. The invisable decimal point is at the back
7 = 7.
it says the prob of spinning no2 = prob of spinning no 2
Well now that is not very helpful!
also, how many numbers are on the the spinner?
your answer is
(5x+2)/6y *9xy^2
this is
$$\frac{(5x+2)}{6}*y *9xy^2$$
See, the first y will be in the wrong place - it is supposed to be on the bottom!
Thanks Radix and Derrickid
Radix: That is a nice interactive web page you have there. Did you build it yourself ?
Derrickid: Your answer is good but do not forgetthe % sign.
No not quite MG because the first y would be on the top.
The division would be done BEFORE the multiplication
Data that give you an exercise of the sine law... would always you darandos angles?
I am sorry but this translation does not make sense.
Perhaps check your spelling and try again.

Sorry but I don't know what you mean.
I have interpreted the question differently from Radix, that is why we have different answers
AND that is why brackets are so VERY important!
$$\\cosx\div tanx \times sinx\\\\ =cosx \div \frac{sinx}{cosx}\times sin x\\\\ =cosx \times \frac{cosx}{sinx}\times sin x\\\\ =cos^2x$$
