Answer 1

Given:

Base radius of conical vessel= 7 cm

Height of conical vessel = 15 cm.

weight of iron per cubic cm = 15 g.

Concept used:

Volume of the Conical Vessel \(=\frac{1}{3}\pi r^2 h\) [Where r is the radius of base and h is height of the conic]

Calculation:

Volume of the conical vessel is = \(\frac{1}{3}\)×π×(7)²×15=770cm³

Weight of the vessel = 770 × 15 =11550 gm = 11.55 kg.

Hence the correct answer is 11.55kg.
