A paddling pool has a diameter of 2 metres and is 40cm high what is the volume
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)
