We will have to use the formula for the area of a trapezoid on this problem, which is (
and 
are the bases of the trapezoid and 
is the height):
All we need to do is substitute the information we are given into our formula:
Now, let's just simplify the equation:
The missing base has a length of 13 units.
The 4's will cancel out, then we have to get rid of the sqrt(16) on the bottom
sqrt(15) / sqrt(16)
sqrt(16) = 4
final answer = sqrt(15) / 4.
the answer is C
Answer: 308cm
Step-by-step explanation: The formula to find the curved surface area of a cylinder is 2πr × h. The formula for curcufrence is 2πr.
So,
2πr (circumfrence)= 44cm.
Height= 7cm.
2πr × h = 44 x 7 = Curved surface area.
Curved surface area= 308cm
