Q1)the ratio of the outer and inner perimeter of a circular path is 2:22.if the path is 5 metre wide then what will be the diameter of the inner circle solution.. simple method. |

Answer» -step explanation:Let the radius of inner PERIMETER be r 1 and the outer perimeter be r 2 So, 2r 1 π2r 2 π = 2223 ⇒r 2 = 2223 r 1 Now from the question, we HAVER 2 −r 1 =52223 r 1 −r 1 =5⇒r 1 =110and r 2 =115Area of path enclosed between two circles are,=π(r 22 )−π(r 12 )=π(115 2 −110 2 )=3535.71Thus the area of path enclosed between the two circles is 3535.71 SQ. m. |
