5. Now solve for
B
for a given area with various number of sides. Enter
A=200
and
N=6
. To find
the distance
B
, move the cursor onto
B
, and then press
ƒ \.
6. Enter
N=8
. To find the distance
B
, move the cursor onto
B
, and then press
ƒ \. Find
B
for
N=9
, and then for
N=10
.
Find the area given
B=6
, and
N=10
,
100
,
150
,
1000
, and
10000
. Compare your results with p6
2
(the
area of a circle with radius 6), which is approximately 113.097.
7. Enter
B=6
. To find the area
A
, move the cursor onto
A
, and then press
ƒ \. Find
A
for
N=10
, then
N=100
, then
N=150
, then
N=1000
, and finally
N=10000
. Notice that as
N
gets large,
the area
A
approaches p
B
2
.
Now graph the equation to see visually how the area changes as the number of sides gets large.
