The function V(r) = 4/3 pi r cubed can be used to find the volume of air
inside a basketball given its radius. What does V(r) represent? *
O
the radius of the basketball when the volume is V
O
the volume of the basketball when the radius isr
O
the volume of the basketball when the radius is V
O
the radius of the basketball when the volume is

the radius of the basketball when the volume is v

Step-by-step explanation:

the radius is 2 times the diameter.

step-by-step explanation:

< xcy ≅ < xby

step-by-step explanation:

in δcax and δbax,

so, δcax ≅ δbax (side-angle-side or sas)

since δcax ≅ δbax, we can conclude < acx ≅ < abx

in δacy and δaby,

so, δacy ≅ δaby (side-angle-side or sas)

since δacy ≅ δaby, we can conclude < acy ≅ < aby

now,

< acy ≅ < aby

=> < acx + < xcy ≅ < abx + < xby

=> < acx + < xcy ≅ < acx + < xby   (since < acx ≅ < abx already proved above)

subtracting < acx from both sides, we get

< acx + < xcy -< acx ≅ < acx + < xby -< acx

cancelling out < acx and -< acx from both sides, we get

< xcy ≅ < xby (proved)
