Find the exact (leave pi) and the approximate ( pi = 3.14 ) circumference for each circle (#s A-F ONLY)

Use the function nest to evaluate p(x) = 1 + x + · · · + x50 at x = 1.00001. (use the matlab ones command to save typing.) find the error of the computation by comparing with the equivalent expression q(x) = (x51 − 1)/(x − 1).

Acircle has the equation (x-2)^2 +y^2 =5. what are the coordinates of the circle's center?

Which addition property is being illustrated below? (type commutative or associative) (6 + 7) + 1 = 6 + (7 + 1)
