My homework is due soon, help!!

A≈50.27

Step-by-step explanation:

( Im gonna replace meters with inches, but that wont change the calculations)

Circle area = π * r² = π * 16 [inch²] ≈ 50.27 [in²]

π ≈ 3.14159265 ≈ 3.14

d = r * 2 = 4 [inch] * 2 = 8 [inch]

50.24

Step-by-step explanation:

A = Area

Radius = 4 (The radius is half of the diameter

Diameter = 8

Pie = 3.14

A = (pie)r^2

A = (3.14)4^2

A = (3.14)16

A = 50.24

the circle one

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
