  1. 75° in radian measure is
    A.π/75 B.75/π C.5π/12 D.12π/5 E.π/30
    3.An arc PQ subtends an angle 60° at the centre O of radius 3 cm. The area of the sector POQ is
    A. 270 〖cm〗^2 B. 3/2 〖cm〗^2 C. 3π/2 〖cm〗^2 D. 3π 〖cm〗^2 E. 180 〖cm〗^2
    4.A sector of a circle has arc length of 8 cm and the area of 16 cm2,then the radius of the circle
    in cm , is
    A. 2 B. 3 C.5 D. 48 E. 12
  2. OAB is a sector of a circle with centre O, radius 8 cm and a perimeter 22 cm. Then the area
    of sector, in square cm is
    (b) E = { x/ x is an even positive integer less than 10 }
    (c) E = { x / x is positive integer, x< 10 and x is a multiple of 2}
    (2) F = { 3, 6,9, 12, 15 , …}
    (a) F = {x/ x is appositive integer that is divisible by 3}
    (b) F = {x/x is a multiple of 3}
    (c) F = {x/x is a natural number that is divisible by 3}
  3. A = {x/x2 + x – 6 } and B = { -3,2}. Is A = B?
  4. A = {x/x is prime number which is less than 10} and B = {x/x2 – 8x + 15 = 0}
    (a) Is A = B (b) Is B⊂ A?
