Answer:
169
Step-by-step explanation:
The surface area is the two-dimensional distance around a figure. In essence, if one was going to wrap the figure in paper, the surface area would be the amount of paper one would need. To find the surface area, one would have to find the area of each individual face, and add up the values.
(7) * (5) = (35)
(9) * (5) = (45)
(7) * (5) = (35)
() * (6) * (9) = (27)
() * (6) * (9) = (27)
Add up all of the values:
(35) + (45) + (35) + (27) + (27) = 169

Answer:
diameter
circumference
diameter
Step-by-step explanation:
First, find the length of the diameter (d) and the length of the circumference of the circle (c).
Next, divide the length of the circumference c by the length of the diameter d and set up an equation
where the ratio equals to (the definition of
)
Then, solve the equation for the circumference c:
Finally, substitute 2 times the radius for the diameter
