![**Problem Statement:**
### Calculation of Mass of a Rotated 3D Shape
**Question:**
What is the mass [kg] of the solid object that will be formed by rotating the y-axis of the shaded area in the figure by 110 degrees?
**Given Data:**
- Density (\( \rho \)) = 7850 kg/m³
- \( a \) = 30 mm
- \( b \) = 75 mm
- \( c \) = 45 mm
- \( d \) = 60 mm
**Diagram Analysis:**
The diagram provided is a 2D plot with the shaded area indicating a geometric region that will be rotated about the y-axis to form a 3D object. The coordinates and dimensions are labeled as follows:
- \( x \) and \( y \) axes are marked.
- From the origin, the x-axis is divided into two distances: \( a \) and \( b \).
- The shaded area extends from \( a \) to \( b \) along the x-axis.
- The height of the shaded area at distance \( a \) is \( c \).
- The height of the shaded area at distance \( b \) is \( d \).
The diagram likely represents a trapezoid or a triangle in the 2D plane, which, when rotated about the y-axis, forms a 3D shape (such as a conical frustum or solid of revolution). The mass calculation will involve determining the volume of the solid and then using the given density to find the mass.
**Notes:**
- The units must be consistent. The given dimensions in millimeters should be converted to meters for the final mass calculation.
- Volume calculation involves applying the principles of solids of revolution.
This problem is framed to help students understand the mathematical concepts of geometry, calculus, and physics in relation to real-world applications. Detailed steps and calculations on the Educational platform would guide learners through solving this type of problem methodically.](https://content.bartleby.com/qna-images/question/9c9e2dde-1c19-44ed-a9d3-170191d095c3/00a4a345-3576-4941-b002-45bb64a5c292/be0dnza_processed.jpeg)
