Step-by-step explanation:
Using the cosine ratio in the right triangle
cosB =
=
=
, hence
B =
(
) = 45°
Answer:
Choice C correct answer.
Step-by-step explanation:
From the question statement, we observe that
d=6 in
r=d/2
so, r=6/2=3 in
The formula to find area is
A = πr²
Putting the value of radius, we get
A = π(3)²
A= 9π in²
