Answer:
39.30 
Step-by-step explanation:
The area of the top surface of the wedge is the same as the area of a sector.
Area of a sector = (θ/
)

where: θ is the central angle, and r is the radius.
Given that: central angle =
, radius = 10 centimetre.
Area of the top surface = Area of a sector = (θ/
)

=

=
x
x 100
= 39.2857
= 39.30 
The area of the top surface of the wedge is 39.30

Non real complex...........
Answer:
C
Step-by-step explanation:
An angle of the measure
should have the same measure as an angle measured
because this is periodic. We can then keep subtracting
from
until we get down to the smallest possible positive radian value:
.
Thus, the answer is C.
