Axial section

Axial section of the cylinder has a diagonal 31 cm long and we know that the area of the side and the area of base is in ratio 3:2.

Calculate the height and radius of the cylinder base.

Correct result:

h =  10.88 cm
r =  14.51 cm

Solution:

312=h2+(2r)2 S1S2=32 2πrhπr2=32 2hr=32 r=2h23  r2=h2+16h222/32=h2(1+1622/32) h=311+1622/32=10.88 cm
r=2h23=14.51 cm



We would be very happy if you find an error in the example, spelling mistakes, or inaccuracies, and please send it to us. We thank you!
