Answer:
the closest to the volume of the container is 115.4 cm³
Step-by-step explanation:
To find the volume of the container, we simply use the formula for calculating volume of a cylinder;
V = π r ² h
Where π is a constant
r is the radius and h stands for height.
From the question given, diameter = 7 cm, but radius if half of the diameter, which implies; r = d/2 = 7/2 = 3.5 cm
h = 3 cm π ≈3.14
We can now proceed to insert our values into the formula;
V = π r ² h
≈ 3.14×3.5² × 3
≈ 3.14 × 12.25 × 3
≈115.395
≈115.4 cm³
Therefore the closest to the volume of the container is 115.4 cm³
Answer:
115.45cm³
Step-by-step explanation:
From the question,A cosmetic container in the shape of a cylinder has a diameter of 7 centimeters and a height of 3 centimeters. Which is closest to the volume of the container?
The volume of a cylinder is pi × r² × h
And if we were given the dimensions of the container as 7 and 3(diameter and height of the cylinder respectively)
We can now find the volume of that cylinder provided we convert the diameter to the radius.
Diameter = radius × 2
Radius = diameter/2
7/2 = 3.5 (that is the radius)
We can now solve for the volume now that we have the height and the radius of the cylinder
V = 22/7 × 3.5² × 3
=115.45cm³
The closest volume of the cylinder is therefore 115.45cm³
