Answer: 9.52cm
Step-by-step explanation:
The data we have is:
Radius = 7cm
Angle of the arc = 1.36 rads
Now, the perimeter of a full circle is equal to:
P = 2*pi*r
Where 2*pi = 6.28 rads
Then the length of an arc of angle A is
P = A*r
then in our case:
P = 1.36*7cm = 9.52cm
Generally a 45 degree angle is the best angle. this yields the smallest triangle with a 6' fence vertical side. As the ladder reaches the wall, two similar triangles are resolved. the 45 degree angle that the ladder makes with the ground yields a 6x6 legged right triangle. Adding 5' to the ground makes the larger 45 degree triangle with a base of 5+6=11' side. Using the formula for Special Triangles, 45-45-90 gives the ladder a 11 times the Squareroot of 2 for its length.
