Answer:
226.19 
Step-by-step explanation:
Vol. of cone = Bh/3 where B is the area of the base(circle) and h is the height of the cone.
r = 3 h = 3
V =
= 9π
Vol. of the cylinder = Bh where B is the base(circle) and h is the height of the cylinder.
r = 3 h = 10 - 3 = 7
V =
= 63π
Total volume = 9π + 63π = 72π = 72(3.1416....) = 226.19
