85cm is 0.85m
Area is 0.85*0.85*pi = 2.26980069222

630/2.26980069222 = 277.557409406

To 4sf: 277.6N/m^2

The area of a 2D form is the amount of space within its perimeter. The pressure on the table is 277.5574 N/m².

What is an area?

The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.

Given that the radius of the table is 85 centimetres. Therefore, the radius of the table in meter can be written as,

1 meter = 100 centimeter

85 centimeter = 0.85 meter

Now, the area of the table is,

Area of the table top = π × r²

                                   = π × (0.85 meter)²

                                   = 2.2698 meter²

Further, it is given that the force of 630 N is applied to the whole table top. Therefore, the pressure on the table can be written as,

Pressure = Force / Area

               = 630N / 2.2698 meter²

               = 277.5574 N/m²

Hence, the pressure on the table is 277.5574 N/m².
