Given:
The area of the cross-section is 55cm².
The volume of the prism is 330cm³.
To find:
The length of the prism.
Solution:
We have,
Area of the cross-section = Area of base = 55 cm²
Volume of the prism = 330cm³.
Let x be the length(height) of the prism.
We know that,
Therefore, the length of the prism is 6 cm.
Answer:
1.92cm
Step-by-step explanation:
Circumference of a circle is computed using the formula:
Where:
r = radius
π = 3.14
Since the radius is the distance of the center of the circle from any point of the circle and the diameter is the measure of a straight line that goes across the center of the circle from one side to the other, radius is half of a diameter. So the diameter = 2r.
We can then use the diameter to solve for the circumference by using the formula"
So we just plug in what we know in the formula:
