Answer 1

$10390.817

Explanation:

Given that :

Sculpture is made in Shape of a cone with :

Height, h = 70 inches

Radius, r = 9 inches

Volume of a cone = 1/3πr²h

Volume = 1/3 * π * 9² * 70

Volume of sculpture = 5937.6101 in³

Cost per in³ = $1.75

Cost of tin for the sculpture :

Cost per in³ * volume of sculpture

$1.75 * 5937.6101 = $10390.817
