HELP!!! I need this answer asap pleas all my points

57.72 ft²

Step-by-step explanation:

Find the area of a semicircle with radius 2 ft.  Subtract this from the area of a triangle with base 8 ft and height 4 ft.  Add this to the area of a rectangle with width 6 ft and length 8 ft.

Area of semicircle =

Area of triangle =

Area of rectangle = width x height = 6 x 8 = 48

Total area = (16 - 6.28) + 48 = 57.72 ft²

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)
