Answer: radius = 3.61 cm
Explanation:
The formula for determining the volume of a cylinder is expressed as
Volume = πr²h
Where
r represents the radius of the cylinder.
h represents the height of the cylinder.
π is a constant whose value is 3.14
From the information given,
Volume = 299 cm³
Height = 7.3 cm
Therefore,
299 = 3.14 × r² × 7.3
299 = 22.922r²
r² = 299/22.922 = 13.044
Taking square root of the left hand side and the right hand side of the equation, it becomes
r = 3.61 cm
