Answer:
A = (16π - 8) cm^2
Step-by-step explanation:
The shaded area is trhe area of the circle minus rthe area of the truiangle,.
A = πr^2 - bh/2
A = π(4 cm)^2 - (4 cm)(4 cm)/2
A = 16π cm^2 - 8 cm^2
A = (16π - 8) cm^2
70% I divided 28/40 and you get 70% after multiplying by 100
Cosine = adjacent/hypothenuse
Adjacent = 28
Hypothenuse = 35
Solution: 28/35
Number one is A. Two is D and I think three is A ( I'm not entirely sure about the last one)
It is called parallel lines when there is two line that never intersect
