Answer:

Step-by-step explanation:

perimeter=2(85)+π(12.5)=220+2×12.5π

=170+25×3.14

=170+78.5

=248.5

distance ran=3×248.5=745.5 yards.

Answer:

Step-by-step explanation:

d= 25 yards ;   r = 25/2 = 12.5 yards

circumference of two semicircle = circumference of circle

=  2πr = 2*3.14*12.5 = 78.5 yards

Perimeter of school truck  = 78.5 + 85 + 85 = 248.5 yards

Distance traveled by  Jasmine = 3* 248.5 = 745.5 yards
