Answer:
Step-by-step explanation: pi r^2
so 42/2 equals 21 radius
volume=22/7 x 21^2
v=1385
The volume of the globe is 38808 cube cm.
Step-by-step explanation:
Given,
The diameter of the globe = 42 cm
The radius (r) = 42÷2 cm = 21 cm
To find its volume.
Formula
The volume of a sphere of radius r = [tex]\frac{4}{3}[/tex]π[tex]r^{3}[/tex]
Now,
Volume = [tex]\frac{4}{3}[/tex]×[tex]\frac{22}{7}[/tex]×[tex]21^{3}[/tex] cube cm
= 388080 cube cm
