The base 2

The base diameter of a right cone is 16cm and it's slant height is 12cm.
A. ) Find the perpendicular height of the cone to 1 decimal place.
B. ) Find the volume of the cone, convert to 3 significant figure. Take pi =3.14

Correct answer:

h =  8.9 cm
V =  599.451 cm3

Step-by-step explanation:

D=16 cm s=12 cm  r=D/2=16/2=8 cm  s2=r2+h2  h=s2r2=12282=4 5=8.9 cm
V=31 π r2 h=31 3.1416 82 8.9443=599.451 cm3
