Answer:
3π units
Step-by-step explanation:
The full circumference of a circle with radius 2 is ...
C = 2πr
C = 2π(2) = 4π
The arc shown is 3/4 of the full circle circumference so is ...
3/4C = (3/4)(4π) = 3π . . . units
Answer:64
Step-by-step explanation:
2*2*2*2=4*4=16. 16*16*16=4,096. 2*2*2*2*2*2=4*4*4=64. 4,096/64=64.

Answer:
m∠A = 144°, m∠B = 36°
Step-by-step explanation:
Supplementary angles are angles that add up to 180 degrees.
Substitute 4(m∠B) for m∠A.
4(m∠B) + m∠B = 180
5(m∠B) = 180
<u>m∠B = 36°</u>
Substitute 36 for m∠B.
4(36) = m∠A
<u>m∠A = 144°</u>
