Option 4 is correct.i.e, ( 256 - ) sq. inch

Step-by-step explanation:

Given : A Square is circumscribed about a circle.

           Radius of Circle = 8 inch.

To find : Area of region inside the square but outside of circle.

From Given figure, we have side of square = Diameter of circle

                                                                        = 2 × 8 = 16 inch.

∴ Area of Required region = Area of Square - Area of circle

                                            = side × side -

                                            = 16 × 16 -

                                            = ( 256 - ) sq. inch

Therefore, Option 4 is correct.

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
