Answer:
D
Step-by-step explanation:
An Integer is a whole number so you can take out B and C and the
![\sqrt{42}](https://tex.z-dn.net/?f=%20%5Csqrt%7B42%7D%20)
is 6.5 so your answer is A
Volume of cone = (pi/3)r^2h
Volume of hemisphere = (1/2) (4pi/3)r^3
we are given r=6/2=3cm, h(cone)=8 cm,
so total volume
=(pi/3)r^2h + (1/2)(4pi/3)r^3
=(pi/3)*3^2*8 + (1/2)(4pi/3)*3^3
=24pi + 18pi
=42pi cm^3
=131.9 cm^3 (approx.)
