Respuesta :
Circumference = 2 x pi x radius
RADIUS 4 RADIUS 5
C= 2 x pi x 4 C = 2 x pi x 5
Both have 2 pi in them, so factor out leaving 4:5 still

The ratio of the radius of two circles is 4:5
C = 2πr
first circle
C = 8π
second circle
C = 10π
answer
ratio of radius 4:5, ratio of circumferences 8π: 10π
C = 2πr
first circle
C = 8π
second circle
C = 10π
answer
ratio of radius 4:5, ratio of circumferences 8π: 10π
