1. V = 3 1 ​ π r 2 H r = 12 c m ; H = 8 c m s u b s t i t u t e t o V : V = 3 1 ​ π ⋅ 1 2 2 ⋅ 8 = 3 1 ​ π ⋅ 144 ⋅ 8 = π ⋅ 48 ⋅ 8 = 384 π ( c m 3 ) 384 π c m 3 ≈ 384 ⋅ 3.14 c m 3 = 1205.76 c m 3 ≈ 1206 c m 3 A n s w er : A
2. A b ​ = 150 f t 2 H = 8 f t V = A b ​ ⋅ H V = 150 ⋅ 8 = 1200 ( f t 3 ) A n s w er : A

The volume of the prism is calculated as 1200 cubic feet using the formula for the volume of a prism, which is the area of the base multiplied by the height. The correct answer is option A: 1200 ft³.
