If a sphere with radius r is inscribed in a cube with edges of length e, which of the following expresses the relationship between r and e ?
a. r=12er=12e
b. r = e
c. r = 2e
d. r=eâr=e
e. r=14e2

r=

Explanation:

when a sphere is inscribed in a cube , a side of the cube equals the diameter of the sphere, hence;

d = e

but d = 2r

2r =e

r=

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.
