Answer:
r = 5
Step-by-step explanation:
The formula for volume of a cone is 
h = 6
V = 50π

r = 5
length = 1/2 w+9
perimeter= 60 =2(l+w)
substitute in for length
60 = 2(1/2 w +9 +w)
60 = 2 (3/2 w +9)
distribute
60 = 3w + 18
subtract 18 from each side
42 = 3w
divide by 3 on each side
14 = w
length = 1/2 w + 9
length = 1/2 (14) +9
7 + 9
16cm
First you will divide 525 by 100. Then you multiply your answer by 4. That will equal 21
