Step-by-step explanation:
A
The circumference (C) of a circle is calculated as
C = πd ( d is the diameter ) , then
C = 3.14 × 8 ≈ 25.12 in
B
The circumference (C) of a circle is calculated as
C = 2πr ( r is the radius )
Here C = 94.2 , then
2πr = 94.2 ( divide both sides by 2π )
r = = 15 cm
Answer:
m∠A ≈ 39.865°
Step-by-step explanation:
C² = 16² + 15² - 2 × 16 × 15 × cos (97°)
=> C = 23.22708085
sin (97°)/23.22708085 = sin A/15
=> sin A = sin (97°) × 15/23.22708085
=> A = (sin (97°) × 15/23.22708085)
=> A ≈ 39.865
