    The canvas of a circus tent is cylindrical in shape up to a height of 5m and above it, it is conical in shape. Its diameter is 140 m and the slant height of the conical part is 60 m. What is the area (in sq. m) of the canvas required to make the tent?

    A) 16300              

    B) 30800

    C) 36200              

    D) None of these

    Correct Answer: D

    Solution :

    \[r=\frac{140}{2}=70\] Total area of the canvas = \[2\pi rh+\pi rl\] =             \[\pi r(2h+l)=\frac{22}{7}\times 70\times (2\times 5+60)\] =     220 \[\times \]70 = 15400 sq. m
