So.. hmm if let's say, Alan is "a" miles from home, then the distance between Rosa and Alan is "a + 1"
thus, check the picture below
€31.65 is the answer to your question
Side of the parallelogram :-
3/5 - 1/5 = 2/5
Height :-
2/5 is the side of rectangle n also forms the height of parallelogram.
Area = bh
= 2/5 × 2/5
= 0.16 foot square
Volume=heiht times area of base
base=circle
area of circle=pir^2
volume=hpir^2
diameter=2r
diametr/2=r
diameter=8.5
find radius
r=8.5/2
r=4.25
h=11.5
subsitute
v=11.5 times pi times 4.25^2
v=11.5 times pi times 18.0625
v=pi times 207.71875
round to hundreth
v=207.72pi in^3
volue=207.72pi in^3
if you want to aprox pi to 3.14 and solve for that then
v=207.72 times 3.14
v=652.24
so
v=207.72pi in^3 or
v=652.24 in^3 aprox (both aer eequatal)
