What we know:
3.14 pi
radius: 7in.
Result units: in^3, this is the results of in used for radius; no conversion needed
Formula volume of a sphere: (4/3)* pi * r^3
(4/3)(3.14)(7)(7)(7)
(4/3)(3.14)(343)
(4/3)(1077.02)
(1.3)(1077.02) \\repeated 3 infinite
1436.026666\\repeated 6inf
The volume of the sphere is about 1436.0266 in^3
No, to be a square each side has to be equal. but all squares are rectangles.
Im very sure it is C, I'm very positive
Answer:
i think it's 15 because if you use 5 and you have to do it by 3 it should be 15
3(x+5)=39
3x+15=39
3x=24
x=8
