Let
C-------> the length of a circumference
C=2*pi*r-----> equation 1
we know that
in this problem-----> <span>the circumference of the foundation is 4 times the radius, increased by 114 ft
</span>so
C=4*r+114------> equation 2
(1)=(2)
2*pi*r=4*r+114------> 2*pi*r-4*r=114-----> r*[2*pi-4]=114---> r=114/[2*pi-4]
r=114/[2*pi-4]-----> 50 ft
the answer is
r=50 ft

Answer:
18.84 cubic inches
Step-by-step explanation:
Height of aluminum cans = 6 inches
Diameter of can = 2 inches
we know that diameter is twice of radius
So,
Diameter of can = 2 inches = 2* radius of can
radius of can = 2 inches/2 = 1 inches
We also know that volume of any cylindrical object is given by
volume of cylinder = 
where h is height of cylinder
and r is radius of cylinder

Amount of soda in can will be equal to volume of can

Thus, 18.84 cubic inches of soda are contained in the given full can.
