The complete question in the attached figure
we know that
[the length of a circumference]=2*pi*r
for r=10 cm
[the length of a circumference]=2*pi*10-----> 62.8 cm
if 360° ( full circle) has a length of---------> 62.8 cm
x--------------------------------------> 20.42 cm
X=20.42*360/62.8-----> x+117.05°-------> x=117°
the answer is<span>
the value of x is 117</span>
°
I think the answer would it's 21
The other diagonal would be 13 feet as well because it is a rectangle.
