Step-by-step explanation:
peter=x
david=x+1.50
x+(x+1.50)=940
x=940-x-1.50

Answer: 3cm
Step-by-step explanation:
The volume of a cylinder is calculated by using the formula:
Volume = πr²h
where,
π = 3.14
r = unknown
h = height = 8cm
Volume = πr²h
3.14 × r² × 8 = 226
25.12r² = 226
Divide both side by 25.12
r² = 226/25.12
r² = 8.9968
r² = 9 approximately
r = ✓9
r = 3
The radius is 3cm
