Question

Find the volume of the composite solid. Round your anwser to the nearest hundredth.

Answer 1

Answer:

226.19 $cm^{3}$

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 = $\frac{\pi *3^{2}*3 }{3}$ = 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 = $\pi *3^{2} * 7$ = 63π

Total volume = 9π + 63π = 72π = 72(3.1416....) = 226.19
