Question

Acone with diameter 4 cm and a height of 8 cm. What is the volume of the figure? Round your answers to the nearest tenth,

if necessary.
a
18.1cm3
b
33.5cm3
с
44.5cm
d
30.2cm

Answer 1

B. 33.5 cm³

Explanation:

d = 4 cm ⇒ r = 2 cm

so:

`V=\frac13\pi r^2\cdot H=\frac13\pi\cdot 2^2\cdot8\approx\frac13\cdot3.1415926...\cdot32=33.51032...\approx33.5\ cm^3`
