Question

The globe used in social studies class has a diameter of 42 centimeters, What is its volume

Answer 1

Answer:

Step-by-step explanation: pi r^2

so 42/2 equals 21 radius

volume=22/7 x 21^2

v=1385

Answer 2

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 = $\frac{4}{3}$π$r^{3}$

Now,

Volume = $\frac{4}{3}$×$\frac{22}{7}$×$21^{3}$ cube cm

= 388080 cube cm
