Answers
Answer:
2514 sq m
Step-by-step explanation:
Given The adjoining figure shows a racing track consisting of two Parallel stitches which is 119 M long and 10m wide it's other two end are a semicircular in a distance between the two parallel stitches is 70 M and also find the distance around the track along its other edge and that is the area of the track.
Now the track resembles two circles with one centre. So
distance will be diameter of inner circle + 2 x width of track
= 70 m + 2 x 10 m
distance = 90 m
Now area of track = area of outer circle - area of inner circle
= 22 / 7 x r₁² - 22/7 x r₂²
= 22/7 x 45² - 22/7 x 35²
= 6364 - 3850
= 2514 sq m
Area of track is 2514 sq m
