Examine the following two circles.

Segment d1 is a diameter of ⨀A and segment d2 is a diameter of ⨀B. Two circles, A and B, with diameters d sub 1 and d sub 2 as described in the problem. Circle B has a larger diameter than circle A.
If CA denotes the circumference of ⨀A and CB denotes the circumference of ⨀B, which equation is true?

A. CB=d1⋅d2⋅CA
B. d1⋅d2=CB⋅CA
C. d1⋅CA=d2⋅CB
D. d1⋅CB=d2⋅CA

Part a what is the area of triangle i? show your calculation. part b triangles i and ii are congruent (of the same size and shape). what is the total area of triangles i and ii? show your calculation. part c what is the area of rectangle i? show your calculation. part d what is the area of rectangle ii? show your calculation. part e rectangles i and iii have the same size and shape. what is the total area of rectangles i and iii? show your calculation. part f what is the total area of all the rectangles? show your calculation. part g what areas do you need to know to find the surface area of the prism? part h what is the surface area of the prism? show your calculation. part i read this statement: “if you multiply the area of one rectangle in the figure by 3, you’ll get the total area of the rectangles.” is this statement true or false? why? part j read this statement: “if you multiply the area of one triangle in the figure by 2, you’ll get the total area of the triangles.” is this statement true or false? why?

Write the summation to estimate the area under the curve y = 1 + x2 from x = -1 to x = 2 using 3 rectangles and right endpoints
