Radius of the inner circle = 13.2 ÷ 2 = 6.6 mm
Area of the inner circle = π (6.6)² = 43.45π mm²
Radius of the larger circle = 6.6 + 4.4 = 11mm
Area of the larger cicle = π(11)² = 121π mm²
Area of the washer = 121π - 43.45π = 243.3 mm²
Answer: 243.3 mm²
Answer:
True.
Step-by-step explanation:
The arcs subtend the same equal angles at the center of the circle, i.e ∠YOZ=∠WOX= 27°. They are also bound by radii. All radii of the same circle are equal thus he two arcs are equal in length. OY= WO= XO= OZ
Therefore the two arcs wx and yz are congruent
Answer:
83
Step-by-step explanation:
get rid of decimals and become 2988/36
divide and get 83
Round 6,254 to 6,300
2 x 6,300 = 12,600
