Answer:
Line segment TS.
Step-by-step explanation:
We have an Unit Circle. The y-coordinate of T is the sine of 
. Therefore, the exact value of 
is TS.
The 3-dimensional shape of a circle is a sphere. In order to solve the volume (v) of a sphere from the radius or diameter of any circumscribed circle within is as follows:
v = 4/3 × pi × r^3, where pi roughly = 3.14
v = 4/3 × 3.14 × (10cm)^3
v = 1.33 × 3.14 × 1000cm^3
v = 4,188.56 cm^3 (cubic cm)
v = 4,189 cm^3 (rounded up)
Step-by-step explanation:
it would be B
