A circular plate has a diameter of 9 inches. What is the area of the plate? Explain the steps you follow to get to your answer

 The area of the circular plate is:  " 63.59 in² " .

Note:

diameter, "d" = 9 in. (given).

radius, "r" = "d/ 2 " = "(9 inches) / 2 " = 4.5 in.

Area of a circle, "A" :

A =  * r²  ;

in which:   "A = Area of circle ("plate"); in units of "square inches"; or "in² " ;

                 " = 3.14 " {approximation we shall use} ;  

                 "r = radius = 4.5 in." ;

Plug in our known values to solve for the area, "A" :

A = (3.14) * (4.5 in)² ;

A = (3.14) * (4.5)² * (in²) ;

A = (3.14) * (4.5) * (4.5) * (in²) ;

A = 63.585 in² ; round to:  " 63.59 in² " .

Step-by-step explanation:

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
