A cylinder and its dimensions are shown below.
1 answer:
Answer:
Step-by-step explanation:
Given a cylinder with the following dimensions
Radius of the Cylinder =12.1 cm
Height of the Cylinder =3.8cm
Volume of a cylinder = Base Area X Height
The base area is a circle, therefore the expression that can be used to find the value of B, (in square centimeters), for this cylinder is given as:

Answer:
The area of the rectangle on the left side is
The area of the bottom rectangle is
The total area of the composite figure will be
Step-by-step explanation:
The area of any given rectangle can be found by multiplying the length of that rectangle by its width. The rectangle on the left side has a length of 9cm but the width is unknown. To find the width, we subtract 6cm from the width of the bottom rectangle: 10cm. And that gives us 4cm.
Therefore, we can now calculate the area to be: length × width = 9cm × 4cm = 36cm²//
The area of the bottom rectangle can be found similarly by multiplying the length: 2cm by the width: 6cm of that rectangle. And the result gives us: 2cm × 6cm = 12cm²//
The total area of the composite figure is calculated by adding the results from the left and bottom rectangles together. And that gives us: 36cm² + 12cm² = 48cm²//
