Question
A solid cone of base radius 5cm and height 6cm IDs made of metal of density 4g/cm cubed, calculate it's mass

Mass = (1/3)πr2h x density
Mass = (1/3)π(5cm)2(6cm) x 4g/cm3
Mass = (1/3)π(25cm2) x 4g/cm3
Mass = (1/3)π(100cm3) x 4g/cm3
Mass = (1/3) x 3.14 x 400g
Mass = 400g
Mass = (1/3)π(5cm)2(6cm) x 4g/cm3
Mass = (1/3)π(25cm2) x 4g/cm3
Mass = (1/3)π(100cm3) x 4g/cm3
Mass = (1/3) x 3.14 x 400g
Mass = 400g

Interesting that the bot cannot do simple arithmetic ...
Mass = (1/3) π (25)(6)(4) g
= 200π g
or
appr 628.3 g
Mass = (1/3) π (25)(6)(4) g
= 200π g
or
appr 628.3 g
