Here, length = circumference
Radius = ?
To find circumference from the given radius, we use the formula
2πr
We will use the same formula for finding radius (We will take π = 3.14)
∴ 100 = 2 × 3.14 × r
∴ r = 100 ÷ (2 × 3.14)
= 100 ÷ 6.28
= 15.92356687898089
Or, approximate answer is 15.92 (If you divide up to two decimal places)
I hope this helps.
