"Find the area and the circumference of a circle with diameter of 8m"

Radius = diameter/2 = 8/2 = 4m

Area of a circle = pi x r^2 = pi x 4^2 = 16pi m^2 ( exact area) or 50.27 m^2

Circumference = pi x diameter = 8pi m ( exact) or 25.12 m

C = 25.12 A = 50.24

Step-by-step explanation:

Circumference formula = dπ

Area formula = πr^2

Circumference:

Plug in:

8π

8 × 3.14 = 25.12

Area:

8/2 = 4

r = 4

Plug in:

πr^2

π4^2

16π

16 × 3.14 = 50.24

Hope this helped.

Answer

the range would be (12, 24, 36, 48)

and the independent variable is x and the dependent is y

Step-by-step explanation:

y=12x

y= 12 * 1 = 12

y= 12 * 2 = 24

y = 12 * 3 = 36

y = 12 * 4 = 48

the range is the set of all y values y = 12x

and domain is the set of all x values y = 12x

so you multiply the each number of the domain by 12

Independent and dependent        y=12x

y is not independent because it varies based on the number chosen for x

A Independent Variable is a variable in an equation that may have its value freely chosen without considering values of any other variable
