Answer:

<h2>R=1.0 cm</h2>

Step-by-step explanation:

V=m/d

V=8.4g/(2g/cm³)=4.2cm³

V=4 π R³/3 ;  π≅3.14

R³ =3V/(4 π)=3*4.2cm³/(4*3.14)=12.6cm³/12.56 ≅ 1.0 cm³

=>R=∛(1.0 cm³) =1.0 cm

How can you tell if the solution is one value,all real numbers,or no solutions
zysi [14]
One value: would be a single valued function, or just one answer.

Real numbers would be: natural numbers, whole numbers, integers, rational numbers (fractions and repeating or terminating decimals), and irrational numbers.

No solution: there is no answer to the question.
