Given the radius of the inscribed circle, the length of any side of the octagon (and any other polygon) is given by;
Side = 2r* tan (180/n) where r=radius and n=number of sides.
For octagon, n= 8 and radius is given by , r= 7/2 = 3.5 ft
Therefore,
Side = 2*3.5*tan (180/8) 2.8995 ft =2.9 ft.
The correct answer is A.

Step-by-step explanation:
using this
t_n = a+ (n-1)d
Answer:
solution given:
volume of lower one[V1]=l×b×h=1.5×0.5×0.5=0.378m³
volume of upper one [V2]=l×b×h=1×0.5×(0.75-0.5)=
0.125m³
total volume=V1+V2=0.378m³+0.125m³=0.503m³
0.503m³ is your answer
