We know that
circumference=2*pi*r
for r=7 in
circumference=2*pi*7------> 14*pi in
if 360° (full circle) has a length of------------ 14*pi in
135°-----------------------------> x
x=135*14*pi/360----------> x=5.25*pi in--------> 16.49 in
the answer is
5.25*pi in or 16.49 in
If 1 cm = 500 miles......then 2.2 cm = (2.2 * 500) = 1100 miles <==
No idea hope you figure it out tho !!
maybe 3?
