Suppose the cost for your glass are as follows: •Region 1 (the area between the square and circle A): $0.10 per square inch
•Region 2 (the area between circle A and circle B): $0.15 per square inch
•Sectors for circle B: One sector will be made from expensive glass that is $0.80 per square inch. The rest of the sectors will be from glass that is $0.20 per square inch.

How much does the glass for region 1 cost?
How much does the glass for region 2 cost?
What is the total cost for the glass for the sectors in circle B?
What is the total cost of the glass for your window?
You have only $100 to spend on glass supplies. Do you have enough money to buy your glass?

step-by-step explanation:

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
