Question

Please help me with this geometry question!!!!!!!!!!!!!!!!!

Answer 1

The answer is 225.19 mm since you convert the 11.2 cm to mm which is 112mm and then use the equation pi x r^2 x h

Answer 2

Volume of cylinder = πr²*h

r=0.8mm = 
h=11.2 cm =112 mm

V=π*0.8²*112 = 71.68π = 71.68π mm³ = 71.68mm³*=
=71.68π mm³ exact value,
or 71.68*π≈225.19 mm³
