You need the following equation
5 pens were purchased.
Since pi is irrational and it is used in the formula, we cannot give an exact answer except in terms of pi (we can give an aproxamation using 3.14 =aprox pi, but it is not exact)
ok
circumfernce=2pir
r=15
circumference=2pi15
circumference=30pi
exact=30pi cm
if you want to aprox pi=3.14 then
aprox circumfernce=94.2 cm
2^2-1
4-1
3
g(2)=3
Hope this helps
