Volume of a cylinder of radius r and heigth h is

Here h is 15 cm and r is 6 cm.
52/38 = 1.368
1.368 x 63 = 86.21
tree is 86.2 feet high
I don’t even know what to say.
Formula for perimeter of rectangle:
P=2(L+w)
P=2L+2w
Here Perimeter, p= 72 ft
And scale factor of length and width=3.5 which means rectangle is enlarged.
So perimeter of rectangle= 3.5 x 72
P=252ft
Answer: 252 ft
I think the answer is r< 18
