Use 3.14 for pi to estimate the area of a circle. the diameter is given. round your answer to the nearest hundredth if necessary
diameter= 16.8
51.12
221.56
448.25
886.23

Area of circle is 221.56 units ² .

Step-by-step explanation:

Formula

Where r is the radius of the circle.

As given

The diameter of a circle is 16.8 unit.

Radius = 8.4 units

Putting all the values in the formula

                                = 221.56 units² (Approx)

Therefore the area of circle is 221.56 units ² .

step-by-step explanation:

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.
