Answer:
4pi
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
where r is the radius
The radius of a circle is found by
r =d/2 where d is the diameter
r = 4/2 = 2
So A = pi (2)^2
pi (4)

Step-by-step explanation:
Answer:
53 degrees
Step-by-step explanation:
Vertical angles are congruent so...
65x-12=43x+10
22x=22
x=1
Then add it into the equation of ∠A
m∠A= 65(1)-12
65-12
53
1/2 (8+4)= 6
1/2(-1+4)= 1.5
1/2 (2+4)= 3
1/2 (4+4)= 4
So the correct answer would be A(8)
