V = pi r^2 h
54 = 3.14 * r^2 * 6
54 = 18.84 r^2
Divide both sides by 18.84
r^2 = 2.866
Square root both sides
r = 1.7

Number of sodas sold = 130
Number of hot dogs sold = 65
Step-by-step explanation:
Given,
Combined number of sodas and hot dogs sold = 195
Let,
x represent the number of sodas sold
y represent the number of hot dogs sold
According to given statement;
x+y=195 Eqn 1
x = 2y Eqn 2
Putting value of x from Eqn 2 in Eqn 1

Dividing both sides by 3

Putting y=65 in Eqn 2

Number of sodas sold = 130
Number of hot dogs sold = 65
