Question

Find volume with full working out thank you ;)

Answer 1

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)
