Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
![**Title: Cylinder Volume Calculation**
**Description:**
The following problem asks for the volume of a cylinder. The problem includes the dimensions of the cylinder and an approximation for π (pi). The solution involves using the formula for the volume of a cylinder and rounding the answer to the nearest hundredth.
**Problem Statement:**
What is the volume of this cylinder?
Use π ≈ 3.14 and round your answer to the nearest hundredth.
**Diagram Explanation:**
The diagram displays a right circular cylinder with the following dimensions:
- Diameter of the base: 22 mm
- Height of the cylinder: 18 mm
**Volume Calculation:**
The volume \( V \) of a cylinder can be calculated using the formula:
\[ V = \pi r^2 h \]
Where:
- \( r \) is the radius of the base of the cylinder
- \( h \) is the height of the cylinder
- π (pi) is approximately 3.14
**Steps:**
1. Calculate the radius ( \( r \) ) of the cylinder.
- The radius is half of the diameter.
- Given diameter = 22 mm
- So, radius \( r \) = \( \frac{22}{2} \) = 11 mm
2. Apply the formula to find the volume.
\[ V = 3.14 \times 11^2 \times 18 \]
3. Perform the calculations:
\[ V = 3.14 \times 121 \times 18 \]
\[ V = 3.14 \times 2178 \]
\[ V \approx 6847.32 \text{ cubic millimeters} \]
Therefore, the volume of the cylinder is approximately **6847.32 cubic millimeters**.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fff9a8e26-af69-42fc-821c-9ae0b96a04a7%2F1f27c15b-b283-40f4-bfb7-ac7bc23aaed7%2F6zbm5n_processed.png&w=3840&q=75)
