Question

What is the volume of the composite figure? Use 3.14 for Round to the nearest hundredth

See attached picture

Answer 1

check the picture below.

so, notice the cone has a radius of 4, height of 8, whilst the cylinder has a radius of 4 and a height of 7.

`\bf \stackrel{\textit{volume of the figure}}{\stackrel{cone}{\cfrac{\pi (4)^2(8)}{3}}~~+~~\stackrel{cylinder}{\pi (4)^2(7)}}\implies \cfrac{128\pi }{3}+112\pi \implies \cfrac{464\pi }{3}`

Answer 2

Answer: D. 485.65 Cubic CM

Explanation:

cone : pi 4^2 8/ 3

Cylinder: pi 4^2 7

128 pi/3 + 112 pi

464pi/3

485.65 CUBE CM Answer = D.
