We know that
the length of a circumference=2*pi*r
for r=8 ft
the length of a circumference=2*pi*8---------> 16π ft
if 2π radians (full circle)-------------------> has a length of 16π ft
3π/4 radians-------------------------------> X
X=3π/4*16π/2π-------------> X=6π<span> ft
the answer is
6</span>π ft

There is no real answer to that question, unless you typed it in wrong.
the answer is in the photo
The correct answer is: 330
Explanation:
The formula for combination is given as follows:
--- (1)
Where n = 11
r = 4
Plug in the values in equation (1) and calculate:

Hence the correct answer is 330.
