Find the length of the rope by which a bull must be tethered in order that it may be able to graze an area of 2464 m2. |
|
Answer» If the bull is tethered by a rope then the area it can graze is a circular area of radius = length of the rope Area of the circle = 2464 m2 πr2 = 2464 m2 \(\frac{22}{7}\) x r2 = 2464 r2 = 2464 x \(\frac{7}{22}\) = 122 x 7 = 16 x 7 x 7 r2 = 42 x 72 r2 = 4 x 7 = 28 m Length of the rope r = 28 m |
