The area of the circle is given as:

Plugging the value of the radius we have that:

Therefore the area in terms of pi is:
10+15+20+25+30+35+40+45+50+55+60+65=450

Answer:
equation of line
x-2y=8
Step-by-step explanation:
equation of line in slope intercept form
(y-y1)={(y2-y1)/(x2-x1)}(x-x1)
or,(y+3)={(-5+3)/(-2-2)}(x-2)
or,(y+3)=(1/2)(x-2)
or,2y+6=x-2
or,6+2 =x-2y
or,x-2y=8
