a land owner needs to fence his semicircular land leaving an opening of length of 3 m for access . the radius of the semicircular plot is 7 m . how long would be the fence in meters ?
perimeter of the semicircle = ï € xd / 2 + d = ï € x 7 + 14 = 22 + 14 = 36 m length of the fence = 36 - 3 = 33 m answer : b
subtract(add(multiply(7, divide(add(add(const_2, const_10), const_10), 7)), multiply(const_2, 7)), 3)
