The straight lines will be joined together to form a single line on the surface of the cone, so 10 will be the slant height of the cone. The curve line will form the circumference of the base. We can compute its length and use it to determine the radius. The length of the curve line is 252/360 * 2 * pi *10 = 14 * pi.These mock contests are similar in difficulty to the real contests, and include randomly selected problems from the real contests.
