A=2πrh+2πr2=2·π·6·25+2·π·6^2 so the answer is D
Answer: 
Step-by-step explanation:
First you put it in to y= mx+b form.
Then you subtract 34 from both sides
Then you divide 8 from both sides
Leaving you with

Answer:
AE = CE = 23; BE = DE = 20
Step-by-step explanation:
Put the values of the variables in their place and do the arithmetic.
AE = 2u+5 = 2(9) +5 = 23
BE = 6v-1 = 6(3.5) -1 = 20
CE = 3u-4 = 3(9) -4 = 23
DE = 8v-8 = 8(3.5) -8 = 20
The diagonals cross at their midpoints, so the quadrilateral is a parallelogram.
