Answer: Option C.
Step-by-step explanation:
The volume of a sphere can be calculated with this formula:
Where "r" is the radius.
You can observe in the figure that the value of the radius of this sphere is:
Then you can substitute this radius into the formula .
Therefore, the volume of the sphere shown in the figure is:
The size of ∠QTW in degrees is 72°. See the explanation below. This is based on the concept of opposite sides in a quadrilateral.
<h3>What is the logic leading to the above result?</h3>QSUWY which is a pentagon is regular that mean:
∠QYW = 108°
The quadrilateral QTWY is a cyclic one. This means that we can apply the rule that states that opposites sides must add up to 180°
Thus, ∠QTW =
180 - 108
= 72°
<h3>What is a quadrilateral?</h3>A closed quadrilateral has four sides, four vertices, and four angles. It is a form of polygon.
In order to create it, four non-collinear points are joined. Quadrilaterals always have a total internal angle of 360 degrees.
