Answer:
7040 yards
Step-by-step explanation:
Because 1 mile = 1760 yards. So 4 x 1760 = 7040.
Its simply 87 + 30, which equals 117.
A= 80
b= 100
c= 100
a is the same as the 80° already shown and to get b you have to subtract 80 from 180
Answer:
102.849
Step-by-step explanation:
the perimeter of the square is just 4 × 18.
for the semi-circle the perimeter should be R(pi + 2)
so the perimeter of a semi circle is 30.849
add both values for the final answer which is 102.849
