Explanation / Answer

for the complete cylinder ::

Radius = R = 135 mm/ 2 = 0.135 m/2 = 0.0675 m

Length = L = 250 mm = 0.250 m

volume of complete cylinder = pi R2 L = (3.14) (0.0675)2 (0.250 ) = 0.00358 m3

for the inner cylinder ::

Radius = r = (135-19-19) /2 =48.5 mm = 0.0485 m

Length = l= 250 mm - 30 mm = 220 mm = 0.22 m

Volume of innner cylinder = pi r2 l = (3.14) (0.0485)2 (0.22 ) = 0.001625 m3

Volume of vase = volume of complete cylinder - Volume of innner cylinder

V = 0.00358 m3 - 0.001625 m3

V = 1.96 x 10-3 m3

mass = density x volume

so mass of vase = 700 x 1.96 x 10-3= 1.372 kg
