A 1.8 m tall man has a waistline of 100 cm. Which measure best approximates the volume of the man when using a cylinder to approximate the man's shape? Question 1 options:

0.06 m³

0.14 m³

0.4 m³

0.72 m³

Waistline 100cm is the circle circumference->calculate radius

100cm=1m=2*r*π

0.5=r*π

0.5/π=r

area of a circle: A=r²π = (0.5/π) ²π=0.25/π m²

circlearea*height=cylinder volume

1.8*0.25/π=0.45/π m³~0.143239 m³

so the second option is the correct one
