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

Samir has collected 35% of the skins on Fortnite. If there are 300 total skins, how many more does he need to collect to be at 5

Nataliya [291]

I believe its 45.

Its hard to explain but what I can say is if you subtract the percentage with the total of the skins you would subtract what you had from there and then you would have 45.
