circumference = 2*pi*r
OpenStudy (calculusxy):
Simply: pi*diameter
OpenStudy (anonymous):
= 2*3.14*40 =6.28*40 = 251.20
OpenStudy (anonymous):
We need to use this formula C= 2* pi *r Here r = 40 plug this value into furmula
OpenStudy (calculusxy):
You just multiply the radius by 2 to get the diameter.
