Well, if the urn is 35cm high and you stand the urn on its side, it will hold that much tall. 35cm is 350mm. However, if you meant millilitres, make sure all dimensions are centimetres and if we assume a cylindrical shape (just given one diameter) the volume formula is pi x r^2 x l. 21/2 is radius of 10.5. pi x 10.5^2 x 35 is 12123ml, or 12.123 litres.
21cm and 16cm.what is the difference in height?
205mm = 20.5cm 21cm > 20.5cm
You can't. There are infinite possibilities. Reread the problem; there must be info you are missing.
1/3 of 21cm = 1/3*21 = 7 cm
A fifth of 21cm is 1/5 x 21 1/5 of 21 is 21/5, which is equal to 4.2 A fifth of 21cm is 4.2 cm
The approximate diameter of a circle whose circumference is 21cm is: 6.68cm
Surface area of a cylinder without the end caps = 2*pi*10.5*21 square cm.
A = 1385cm2
2200mm
area of a circle and the question is d=21cm
A = 346.36 cm2
A = 1,385.4 cm2
