Answer:
Circ=37.704, Area= 112.112
Step-by-step explanation:
Circumference= pi *Diameter
Taking pi=3.142, Diameter=12
Circ=3.142*12=37.704
Area= pi * r^2
Area= 3.142*6*6=112.112
Provided that the triangle looks like this:
A| \ | \ | \ | \ | \ b| \ 20 | \ | \ | \ | \ |_______40\C a B
Then using the the equation to solve for line segment AC (or b on the diagram):
sin(40) = b/20
b = 20 * sin 40
b = segment AC = 12.9 units
The answer would be D) no, these triangles are not similar. I'm pretty sure they would be similar if one of the answer choices said ΔABC ~ ΔCED
