How do you find the total height of a cylinder for the following problem?

Question

A 1.00 L graduated cylinder has an inside diameter of 8.24. There is a 53-mm ungraduated portion at the top. What is the total height of the cylinder in centimeters?

Answer 1

The 1000ml or 1000cm³ measuring cylinders with which I am familiar have an internal diameter of 8.24cm

Volume = π*r²*h

1000= 3.14*4.12²*h

h = 1000/3.14*16.97

h = 18.76cm

Plus the 5.3cm unmarked height = 18.76+5.3= 24.1cm

Total height = 24.1cm.

Answer 2

V = 1.00 dm^3 = 3.14 ( r )^2 x h

You forgot the meansure of the diameter 8.24 ?

if diameter is 8.24 dm => r = 4.12 dm

1.00 = 53.3 x h

h = 0.0188 dm

total height = 0.0188 dm + 0.53 dm =  0.549 dm
