@NerdyChick16, can you help me?

otherworldly · Answer

srry i had to go for a bit does the question tell u what the radius is

nvidiaintely · Answer

Nope :(

nerdychick16 · Answer

would it be 4.19×106 ? if not I dunno :\

nvidiaintely · Answer

Hmmm....this is hard.
Let me re-open this.

otherworldly · Answer

V= 4/3 pi r^3 
A= 4 pi r^2
since we already know what the surface area is we just plug it in so
100 pi= 4 pi r^2
ignore the pi and divide by 4 and it will be 
25= r^2
so the radius is 5 because 5 x 5 = 25
now that we know what the radius is plug it in the volume formula for sphere

otherworldly · Answer

so V= 4/3 pi 5^3
simplified: V= 4/3 pi 125
ignore the pi again and multiply 4/3 x 125
