Answer:
Step-by-step explanation:
area of triangular face = ½·6·4 = 12 cm²
volume of prism = area of triangular face × length of prism = 12×7.5 = 90.0 cm²
:::::
radius of circle = 2.5/2 = 1.25 cm
area of circle = π1.25² = 1.5625π cm²
volume of cylinder = area of circle × length of cylinder = 1.5625π×7 = 34.4 cm²
