Answer: Hope this helps :))
Step-by-step explanation:
Step 1: Find the circumfrence
Circumfrence= 2πr
R= 6.25
Plug into the formula:
2πr
2x6.25x3.14
= 39.25 , which rounds to 39.3, further rounds to 39.
Step 2: Find the diameter
Diameter: the length across the whole circle
Radius: length across 1/2 the circle. We know that the radius (r)= 6.25, so we must multiply this by 2 to find the total. Another way is to just do 6.25+6.25, since its 1/2 and 1/2.
6.25x2= 12.5
6.25+6.25= 12.5
Diametr= 12.5
Step 3: Write the ratio.
Circumfrence: diameter
39: 12.5
