Ответ:
5 cm
Step-by-step explanation:
The formula for the volume of a cylinder is
V = πr²h
Data:
V = 1726 cm³
h = 22 cm
Calculation:
1726 = 3.14 × r² × 22
1726 = 69.08r²
Divide each side by 69.08
24.99 = r²
Take the square root of each side
r = 4.999 cm ≈ 5 cm
The approximate radius of the cylinder is 5 cm.
