A1.8 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

The answers are 20,30,80,180,960,890,1230,4560. on the first row
