(43 PLUS 5 MORE POINTS!!)The highschool stadium contains a track that surrounds a soccer field. The soccer field is 100 yards long and 70 yards wide.
-What is the area of one of the semicircles at either end of the track?
-The school decided to cover the semicircles with grass to create a space for stretching and other activities. How many square yards of grass will the school need to cover the entire circle?
-What is the distance around one of the semicircles at either end of the soccer field?
-What is the distance around the inner lane of the track (i.e,, the lane closest to the soccer field)?
PLEASE HELP, IT WOULD BE GREATLY APPRECIATIVE.

Given : The highschool stadium contains a track that surrounds a soccer field. The soccer field is 100 yards long and 70 yards wide.
The school decided to cover the semicircles with grass to create a space for stretching and other activities.
To Find: area of one of the semicircles at either end of the track
How many square yards of grass will the school need to cover the entire circle?
Solution:
Diameter of semicircle = 70 yards
Radius of semicircle = 70/2 = 35 yards
Area of semicircle at one end = (1/2)πr²
= (1/2)(22/7)35²
= 1,925 sq yards
area of one of the semicircles at either end of the track = 1,925 sq yards
square yards of grass will the school need to cover the entire circle
= 2 x 1,925
= 3850 sq yards
distance around one of the semicircles at either end of the soccer field = πr = (22/7) 35 = 110 yards
distance around the inner lane of the track = 100 + 100 + 110 + 110
= 420 yards
