If the "problem of 3 and a number " is multiplying:
If it's about adding:
Scenario A: If it's 3 and z, then that means it's 3, and we're adding 4, so it's
(make sure to put () around the 3
!)
Scenario B: If 3 and z is also 3+, then the equation is
(also use () on this too!)
Angle = 36 degrees = 
= 
now, radius = 10 cm
so arc = radius x angle = 10 x pi/5 = 2pi = 6.28 cm
now, radius = 10 cm
so arc = radius x angle = 10 x pi/5 = 2pi = 6.28 cm
