A ≈ 153.1 units²

Step-by-step explanation:

area (A) of rectangle is

A = length × breadth = 16 × 8 = 128 units²

The diameter of the circle is 8 , then radius = 8 ÷ 2 = 4

area of semicircle = × πr² ( r is the radius )

                              = × π × 4²

                             = × π × 16

                             = 8π

Then area of figure = 128 + 8π ≈ 153.1 units² ( to the nearest tenth )

I hope it helps you !!..✌️

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

answer: no, but if it does it's a obvious pattern.
