Answer:
8π
Step-by-step explanation:
A=180/360×π(4^2)
A=1/2×16π
A=8π
Answer:
16.1 Inches
Step-by-step explanation:
In ΔKLM,
∠K+∠L+∠M=180°
∠K+161°+18°=180°
∠K+179°=180°
∠K=180°-179°=1°
To determine k in the diagram, we use the Law of Sines.


k X Sin 161°=300 X sin 1°
k=(300 X sin 1°)÷sin 161°
k=16.1 inches (correct to the nearest tenth of an inch)
