Answers
Answer:
- Area over which the cow can graze is 154 m².
Step-by-step explanation:
Given information,
A cow is tied to a pole on one end of a rectangular park with a string of length 14 m. Find the area over which the cow can graze. (Take π = 22/7)

¤ Here according to the question, cow is tied to a pole on one end of a rectangular park with 14 m long string. We know that, angle on each of rectangle is right angle i.e, 90°. Let's assume area grazed as area of quadrant of circle and length of string as radius of quadrant of circle. ¤
Using formula,
✪ Area of quadrant = 90/360 × πr² ✪
Where,
- π denotes Pi
- r denotes radius
We have,
- π = 22/7
- r = 14 m
- Area of quadrant = ?
Putting all values,
➧ Area of quadrant = 90/360 × 22/7 × 14²
➧ Area of quadrant = 9/36 × 22/7 × 14×14
➧ Area of quadrant = 1/4 × 22/1 × 2 × 14
➧ Area of quadrant = 1/4 × 44/1 × 14
➧ Area of quadrant = 1/4 × 44 × 14
➧ Area of quadrant = 1/1 × 11 × 14
➧ Area of quadrant = 1 × 11 × 14
➧ Area of quadrant = 11 × 14
➧ Area of quadrant = 154 m²
- Hence, area over which the cow can graze is 154 m².
Additional information,
↠ Area of minor sector
ㅤㅤㅤㅤㅤ→ θ/360 × πr²
↠ Area of major sector
ㅤㅤㅤㅤㅤ→ πr² - Area of minor sector
↠ Area of minor segment
ㅤㅤㅤㅤㅤ→ Area of corresponding sector - Area of corresponding ∆
↠ Area of major segment
ㅤㅤㅤㅤㅤ→ πr² - Area of minor segment
↠ Length of arc of a sector
ㅤㅤㅤㅤㅤ→ θ/360 × 2πr
↠ Area of circle
ㅤㅤㅤㅤㅤ→ πr²
↠ Circumference of circle
ㅤㅤㅤㅤㅤ→ 2πr
