Answer 1

Vsphere=(4/3)(π)r³
Vcylinder=(h)(pi)(r²)
Vcone=(1/3)(h)(pi)(r²)


7.
d/2=r, 10/2=5
V=(4/3)(π)(5³)
V=(500π)/3
aprox 523.598666 in³

8.
h=30
r=15
V=(30)(π)(15²)
V=6750pi aprox 21205.746 ft³

9.
d=8
d/2=8/2=4=r
h=12
V=(1/3)(12)(π)(4²)
V=64π aprox 201.06188 cm³

10.
V=volume

r=radius

π=aprox 3.141592, it is the ratio of the circumference to the diameter

h=height
