Question

What is the answer. Please dont send me ‘links’. I seriously need help.

Answer 1

Total Volume of composite figure = 635.2 cm³

Steps:

• 1.

CV = h×3.14×(d/2)²

CV = 5×3.14(8/2)²

CV = 5×3.14(4)²

CV = 5×3.14×16

CV = 5×50.24

CV = 251.2 cm³

• 2.

RV = h×w×l

RV = 4×8×12

RV = 4×96

RV = 384 cm³

• 3.

TV = CV + RV

TV = 251.2 + 384

TV = 635.2 cm³
