A high school track is shaped as a rectangle with a half circle on either side.

A rectangle has a length of 85 yards and width of 25 yards. 2 semicircles with diameters of 25 yards are on each end of the rectangle.

Jasmine plans on running three laps. How many yards will Jasmine run? Use 3.14 for Pi.
248.5 yd
490.5 yd
725.5 yd
745.5 yd
PLEASE HELP

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.

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

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.

answer: 40392

step-by-step explanation:

10098 x 4 = 40392
