The radius of a circle is increase twice then its perimeter is increase |
|
Answer» Why no Yes perimeter get doubledIf radius is r then perimeter of circle(p) = 2πr And if radius(r) increased twise thenNew radius(R) = 2(r)New perimeter of circle(P)= 2πR = 2π(2r) = 4πr =2(2πr)And the 2πr is equal to the old perimeter of circle(p) So new perimeter of circle = 2pSo new perimeter of circle is double if we increase the radius twise No |
