Hey there we cannot see the question :D Sorry about that I would answer but I cannot!

Answer: radius = 6.5millimeters; Area = 132.7m²
Step-by-step explanation:
The circumference of a circle = 2πr
The area of a circle = πr²
The circumference of a button is 40.8 millimeters. Then we can get the radius, thus will be:
Circumference = 2πr
40.8 = 2 × 3.14 × r
40.8 = 6.28r
r = 40.8/6.28
r = 6.5
Radius is 6.5 millimeters
Area = πr²
Area = 3.14 × 6.5 × 6.5
Area = 132.7m²
For this case, we have that by definition, the proportions can be expressed in different ways. Example, if we have a dog and three cats:
75%: It's percentage
0.75: In decimal (75% are cats)
: In fraction. (There are
of cats)
: Using ":" to separate sample values. (For every three cats there is a dog)
Care should be taken with the proportions, always multiplying the numbers in the proportion by the same value.
