Let's examine your answer choices:
A The arc length of the smaller circle is half the arc length of the larger circle.
Hmmmm that can't be right. The arc length of a 60° angle must be equal to the arc length of another 60° angle!
Hey! Would you look at that! With that knowledge you can answer the question!
The correct answer is B because the arc length of a 60° angle is equal to the arc length of another 60° angle!
So the correct answer is B! Hope that helps!
Answer:
Step-by-step explanation:
The applicable rule of exponents is ...
a^(-b) = 1/(a^b)
Of course, an exponent is used to signify repeated multiplication.

3^(-2) = 1/3^2 = 1/(3·3) = 1/9
__
4^(-3) = 1/4^3 = 1/(4·4·4) = 1/64
__
2^6 = 2·2·2·2·2·2 = 64
The measure of m∠3 =20°
Step-by-step explanation:
Given that:
m∠1 = (3x-5)° and m∠2= (2x+15)° then
∠ABE= m∠1= opposite vertical angles are equal
∠ABE =∠BEF = alternate angles
m∠2= ∠BEF = opposite vertical angles are equal
Thus m∠1 = m∠2
(3x-5)° = (2x+15)°
3x-5=2x+15
3x-2x=15+5
x=20°
m∠2 and m∠3 are opposite angles in the parallelogram DEHG which are congruent thus m∠3 =20°

8b - 1 = 24b + 4
Subtract 8b from both sides.
-1 = 16b + 4
Subtract 4 from both sides.
-5 = 16b
Divide by 16 on both sides.

The answer is 13.76 sq inches first you find the area of the plywood 8x8=64 then you minus the area of the circle cut out. So that formula is pir^2 and that is 3.14x16=50.24 now minus it off plywood area 64-50.24=13.76 square inches
