Answer:
Surface area of a cylinder = 2πrh+2πr²
r = radius
h = height
Step-by-step explanation:
AThe asnwer is use a clacuerereter
Step-by-step explanation:
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
The answer is ....................
X=5
Y=3
