Answer:
a=21
b=69
c=42
d=138
Step-by-step explanation:
c is supplementary to d (which is 138), so c=180-138= 42.
angle b is on the edge of the central angle 138, so b is 1/2, therefore, b=69.
angle a is complementary to angle b because any triangle that includes the diameter is a right angle, so angle a=90-69=21.
In the beginning operations are performed with multiplication,,,so
100x100=10.000+100=
10.100result…

Answer:
A ≈ 12.57
Step-by-step explanation:
You have to take the formula: A = πr^2
1) Plug in what you know: A = π•2^2
2) π = 3.14 and 2^2 = 4
3) Multiply to get: 12.56637
4) Round
A ≈ 12.57
