Question

Work out the volume of this half-cylinder.

Give your answer in terms of π.
The diagram is not drawn to scale.

Answer 1

Vhc = 401.92 cm3

Explanation:

Vcylender = Pi*r2*h

Vhalfcyldr = (Pi*r2*h)/2

then

h= 16cm

r = 8cm/2 = 4cm

then

Vhalfcylinder = ((3.14)*(4)2*16) / 2

Vhc = 401.92 cm3
