i. Let t be the line tangent at point J. We know that a tangent line at a point on a circle, is perpendicular to the diameter comprising that certain point. So t is perpendicular to JL
let l be the tangent line through L. Then l is perpendicular to JL ii. So t and l are 2 different lines, both perpendicular to line JL.
2 lines perpendicular to a third line, are parallel to each other, so the tangents t and l are parallel to each other.

Answer: (A) 352 π units^2
Explanation in image.
Knowledge point:
Geometry - cylinder area formula
It is true only whenever x tends to 0(zero)
it is not importent that x be in radian or in degree.
Its also 40°30' because the median is also a bisector in isosceles triangle
