Answer:
4,116.9mm² (rounded up to nearest one decimal point)
Step-by-step explanation:
Diameter of a circle is 72.4mm (where mm stands for millimeters)
Area of a circle is given by πr²
Radius (r) = 72.4mm ÷ 2 = 36.2mm
Area = π × (36.2mm)² = 4,116.868677mm²
That is 4,116.9mm² (rounded up to one decimal point)
Answer: 18482
8% of 17113 is 1369
1369 + 17113 = 18482
16.25
6.5 + 5 = 32.5/2 = 16.25
