Answer:

1). Diameter of the circle is given to be : 3.7 meter

So, The radius will be 1.85 meter

Now, we need to find the area of the circle.

So, Area of the circle = π × radius²

⇒ Area of the circle = π × 1.85²

⇒ Area of the circle = 3.4225π meter²

Hence, The correct option is A). 3.4225π meter²

2). Radius of the circle = 6 inch

Central angle = 165°

And we need to find the area of the sector

\implies\text{Area of the sector = }\frac{\theta}{360}\times \pi\times radius^2\\\\ \implies \text{Area of the sector = }\frac{165}{360}\times 3.14\times 6^2\\\\\implies \text{Area of the sector = }51.8\:inches^2

Therefore, The correct option is B. 51.8 inches²
