Answer:
3.7
Explanation:
the formula for the circumference of a circle is:
2πr, or twice the radius multiplied by pi
C = 2πr
substitute 23.2 for 'C'
23.2 = 2πr
we are trying to isolate the 'r'
divide each side by 2 to get:
23.2/2 = πr
11.6 = πr
11.6/π = r
if we use 3.14 as the value of pi we get:
11.6/3.14 = r
3.69, rounded to nearest tenth would be 3.7
