Paula measures a prize wheel at a carnival and calculates that it has an area of 3.14 square feet. what is the prize wheel's diameter?

The diameter of the prize wheel is 2 feet.

Step-by-step explanation:

Given,

Area of the prize wheel =

Since the prize is a wheel and wheel is in the shape of circle.

So we use the formula of area of circle to calculate the radius.

Let the radius of the circle be x.

On substituting the value of area and radius, we get;

So the radius of the circle = 1 feet

And we know that the diameter is twice of radius of the circle.

Thus the diameter of the prize wheel is 2 feet.

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
