Area of the shaded region is 2868.61 square inches.

Solution:

Diameter of the smaller circle = 20.4 in

Radius of the smaller circle = 20.4 ÷ 2 = 10.2 in

Area of the smaller circle = πr²

                                          = 3.14 × (10.2)²

Area of the smaller circle = 326.6856 in²

Radius of the larger circle = (10.2 + 21.7) in = 31.9 in

Area of the larger circle = πR²

                                        =3.14 × (31.9)²

Area of the larger circle = 3195.2954 in²

Area of shaded region = Area of larger circle – Area of smaller circle

                                      = 3195. 2954 in² – 326.6856 in²

                                      = 2868.6098 in²

                                      = 2868.61 in²

Area of the shaded region is 2868.61 square inches.

i know the answer is 3

step-by-step explanation:

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )
