as the following pic you can see the answer.
#diameter is 8 so radius is 4
V = ⁴⁄₃πr³ is the formula for the volume of a sphere
Rectangle prisms have 6 flat surfaces.
The expression θ = - 50° ± i · 360°,
represents the family of all angles <em>coterminal</em> with - 50° angle.
<h3>What is the family of angles coterminal to a given one?</h3>
Two angles are <em>coterminal</em> if and only if their end have the <em>same</em> direction. Two <em>consecutive coterminal</em> angles have a difference of 360°. Then, we can derive an expression representing the family of all angles <em>coterminal</em> to - 50° angle.
θ = - 50° ± i · 360°, 
The expression θ = - 50° ± i · 360°,
represents the family of all angles <em>coterminal</em> with - 50° angle.
<h3>Remark</h3>
The statement is incomplete and complete form cannot be reconstructed. Thus, we modify the statement to determine the family of angles coterminal to - 50° angle.
