Answer to Problem 4CA
The amount of fabric needed is 298.45 square inches of fabric.
Explanation of Solution
Calculation:
The angle of the sector in radians is
Area of the larger sector
Area of smaller sector
Thus, area of the lampshade is
Thus, the amount of fabric needed is 298.45 square inches of fabric.
Conclusion:
Thus, the amount of fabric needed is 298.45 square inches of fabric.

- You are given a plane Π in R3 defined by two vectors, p1 and p2, and a subspace W in R3 spanned by twovectors, w1 and w2. Your task is to project the plane Π onto the subspace W.First, answer the question of what the projection matrix is that projects onto the subspace W and how toapply it to find the desired projection. Second, approach the task in a different way by using the Gram-Schmidtmethod to find an orthonormal basis for subspace W, before then using the resulting basis vectors for theprojection. Last, compare the results obtained from both methodsarrow_forwardPlane II is spanned by the vectors: - (2) · P² - (4) P1=2 P21 3 Subspace W is spanned by the vectors: 2 W1 - (9) · 1 W2 1 = (³)arrow_forwardshow that v3 = (−√3, −3, 3)⊤ is an eigenvector of M3 .
