Outside Circle;
r = d÷2 v = pi.r.r.h
r = 10÷2 v = 3.14x5x5x40
r = 5cm v = 3140cm³
3140cm³-2009.6cm³ = 1130.4cm³
Inside Circle;
r = d÷2 v = pi.r.r.h
r = 8÷2 v = 3.14x4x4x40
r = 4cm v = 2009.6cm³
r = d÷2 v = pi.r.r.h
r = 8÷2 v = 3.14x4x4x40
r = 4cm v = 2009.6cm³
Good job Chris. Next time, try to add explanation using words. Keep up the good work.
