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)
3.5x + 4.8 = (3 + 0.5) x+ (4+ 0.8) = 3.x + 0.5x + $ 0.8
