81000 would be your answer
It's 72
the measure of exterior angle of any regular polygon = 360/number of sides = 360/5 = 72°
We are given the diameter of the circle, I assume. In this case, the formula of the area of the circle is expressed as A = pi d^2/4. where pi is a constant. The only option taht makes sense here is C. 6.25 in2. This should have the constant pi on it.
Step-by-step explanation:
y=-2x+2+x+1
y=_2x+x+2+1
y=x+3
