Find volume with full working out thank you ;)

Answer:
2110 cm³
Step-by-step explanation:
Volume = V1 + V2,
Where V1 is the volume of the pyramid, and V2 is the volume of half cylinder
V1 = ⅓×(Base area)×height
V1 = ⅓×(12.6×21.5)×8.5 = 767.55
V2 = ½×(pi×r²×h)
r = 12.6÷2 = 6.3
V2 = ½×(pi×6.3²×21.5) = 1340.415
Volume = V1 + V2
= 767.55 + 1340.415
= 2107.965
= 2110 cm³ (3 sf)
