Answer:
205 pages.
Step-by-step explanation:
We have been given that a postcard collector has 1,230 postcards. She display them on pages that hold 6 cards each.
To find the number of pages required to display 1,230 postcards, we will divide 1,230 by 6.
Therefore, the collector needs 205 pages to display 1,230 postcards.
Answer: 50.26548 (50.27)
Circumference = 2 x π x r(radius)
Diameter = 2 x r(radius)
C = π x 16 = 50.26548
x=6
x+3=9
x+3-3=9-3
x=17
(5x-58)=(2x-7) ->(because of cosine-rule)
3x=51
