The areas of the two watch faces have a ratio of 16: 25. what is the ratio of the radius of the smaller watch face to the radius of the larger watch face?

4:5

Step-by-step explanation:

Let r be the radius of small watch

Area of small watch=π

Let R be radius of larger watch= π

Area of larger watch= π

It is given that the ratio of their areas= 16:25

=

π: π= 16:25

=

r:R= 4:5

Hence, the ratio of their radii= 4:5

Hence, the correct answer is 4:5
