Answer:
D
Step-by-step explanation:
Answer:
= 3052.08 cm^3
Step-by-step explanation:
Volume of a sphere is given by
V = 4/3 pi r^3
We know the diameter is 18
d = 2r
18 = 2r
Divide each side by 2
18/2 =2r/2
9 =r
V = 4/3 pi 9^3
V = 4/3 pi (729)
V = 972 pi
Approximating pi by 3.14
V =972 (3.14)
= 3052.08 cm^3

Since we've established before that a square can be a rhombus or a
parallelogram, the criteria that two adjacent angles must be equal holds
for both. This shape can be a trapezoid in the special case where one
pair of sides is congruent and parallel and the other is congruent but
creates a shape such that opposite angles are supplementary and adjacent
angles are congruent.
