What is the area of a circle with the diameter of 8 units

A = 16pi or 50.24 units^2

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

We need to find the radius

r = d/2 where d is the diameter

r = 8/2 =4

Substituting into the equation for area

A = pi (4)^2

A = 16pi

We know pi can be approximated by 3.14

A = 16(3.14)

A =50.24 units^2

answer: the answer is simply nothing.

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
