  • 2πr =2r = 15br /r = 7/2br /πr2 = 22/7 x 7/2 x 7/2 = 38.5 m2br / div /div

    0

  • Answer will be Option (d) (2πr =2r) = 15 r = 7/2 πr2 = 22/7 x 7/2 x 7/2 = 38.5 m2

    0

  • 2 * pi * r - 2 * r = 15br /r = 7/2br /pi * r * r = 38.5 m2 is the answer

    0

  • 2πr - 2r = 15br /r = 14/(2π - 2)br /r = 14*7/30br /AREA:br /πr^2 = (22*49*49)/(7*15*15)br /= 33.53
