A=pi r^2
A= pi(4^2)
A=pi(16)
A=50.265...ft^2
2A=100.5309...ft^2
C=pi d
C=8pi
C=25.1327...ft^2
25.1327...(50)= 1256.637...
1256.637...+100.5309...=1357.167... so the surface area of the tan is about 1357.2 ft^2
75.6 will be the closest answer
Answer:
D
Step-by-step explanation:
The diagram is attached.
Looking at the diagram, we want the side "opposite" of the angle given and the side "adjacent" is given.
Which ratio relates opposite and adjacent? It is Tan.
We can use trigonometry and tan ratio to solve for the distance "x":

D is the correct answer.
