Let
x---------> <span>the width of the gravel path
we know that
72=(2x+6)*(2x+7)----> 72=4x</span>²+14x+12x+42-------> 4x²+26x-30=0
using a graph tool-----> to resolve the second order equation
see the attached figure
the solution is
x=1
the answer is
the width of the gravel path is 1 ft

Answer:
135 degrees
Step-by-step explanation:
step 1
Find the circumference of the circle
The circumference is equal to
we have
substitute
step 2
Remember that the circumference of the circle subtends a central angle of 360 degrees
so
using proportion
Find out the measurement of the central angle (in degrees) that intercepts an arc with a length of 9π/2 ft
