    3. PQ and QR are not of the same length.
      Here's the working:
      ∠PRS= 180- 2(180-110)
      =180- 2(70)
      =180-140
      =40°
      I got 70° from subtracting 110° from 180° because PST is a straight line. Then, I multiplied it by 2 because triangle PRS is an isosceles triangle (2 sides of the same length).

      In a circle, opposite angles is equal to 180°. Thus,∠QRS +∠QPS = 180°
      From there we know that∠QRS = 42°+40°=82°
      Therefore, 82°+∠QPS= 180°
      ∠QPS=180°-82°
      =98°
      Hence,∠QPS= x =98°
      Answer: B

      Your argument is invalid. I apologise for my bad English.

    1. radius of the base of the cone (circle): 10/2= 5cm
      slant height of the cone:√ 12²+5²= 13cm (I refer this slant height as s)
      Formula for surface area of cone:
      Ï€r²+Ï€rs=total surface area of cone
      5²Ï€+(5x13)Ï€
      25Ï€+65Ï€
      =90Ï€
      Answer: B
