Y=1/2x^3 A patch in the shape of the region shown above is to be sewn onto a flag. If each unit in the coordinate system represents one foot, how much material is required for the patch?

a.

15.525 ft²

c.

10.525 ft²

b.

15.125 ft²

d.

10.125 ft²

the perimeter is increased by a factor of 2

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
