We know that
[area of a circle ]=pi*r²
diameter=4 in
r=4 in/2-----> 2 in
so
area=pi*2²-----> area of the circle=4*pi in²
the answer is
the area, in square inches, of the circle is <span>3.14 • 2²</span>
the value of x is 90 degrees and the the value of y is 180 degrees
83-73 will make up to 155
= 204800. 204800 / 
= 800.
