Answer:
1/89
Step-by-step explanation:
Answer:
4.71 units
Step-by-step explanation:
The formula for arc length =
2πr × θ/360
From the above question,
r = QR = 3 units
θ = angle QRS= 90 = 90°
The length of the arc is calculated as:
2 × π × 3 × 90/360
= 4.7123889804 units
Approximately to the nearest hundredth = 4.71 units
Just subsitute 10 for Q
pemdas
(Q*5)=(10 times 5)=50
(50)+20=70
the answer is 70
