Answer:
Option A)724 square centimeters
Step-by-step explanation:
we know that
The surface of the prism is equal to the area of its six rectangular faces
The surface area is equal to
where
B is the area of the base
P is the perimeter of the base
H is the height of the prism
we have
<em>Find the area of the base B</em>
<em>Find the perimeter of the base P</em>
<em>Find the surface area SA</em>
Area = 200.96 cm^2
r = square root of area / 3.14
radius r = 7.9967778595084
Answer:
9/41
Step-by-step explanation:
The base line is
The square root of (41*2-40*2),=9
Thus, cosC=9/41
