To calculate the area of museum.

Answer to Problem 41SGR
Explanation of Solution
Given Information:
Formula Used:Area of
Calculation:
In given figure, it shows 1 square, 4 rectangle and 4 semi-circle.
So, Area of museum= Area of square + Area of 4 rectangle + Area of 4 semi-circle.
So, first calculate area of square.
Area of square =
As Side = 60 ft.
Area of square =
Area of square=
Now, calculate area of rectangle =
Length = 60 ft. and Breadth = 20 ft.
Area of rectangle =
Area of rectangle =
Hence, for calculate area of 4 rectangular
Area of 1 rectangle =
Area of 4 rectangle =
Area of 4 rectangle =
Now, calculate area of semi-circle =
Radius = r.
Area of semi-circle =
Now, radius is of 30 ft.
Area of semi-circle =
Now,
Area of semi-circle =
Area of semi-circle =
Hence, for calculate area of 4 semi-circle
Area of 1 semi-circle =
Area of 4 semi-circle =
Area of 4 semi-circle =
Area of museum = Area of square + Area of 4 rectangle + Area of 4 semi-circle
Area of museum=
Area of museum=

- You are provided with three 2D data points, p1, p2 and p3. Solving A C = B for C provides youwith the coefficients of a natural cubic spline curve that interpolates these points.Additionally, you have been given A and B, but some elements are missing. Moreover, the last two rowsof A are entirely absent. Your task is to determine and fill in the missing elements. For the last two rows,enforce a zero tangent at the beginning (in p1) and a not-a-knot boundary condition in p2. The matricesA and B are given as follows:Explain how to find the entries of A and B . How would you adapt these matrices if the data pointswere 3D? What if your spline should go through five data points? How many “extra rows” would there thenbe (with “extra” meaning “in addition to securing C2-continuity”)?arrow_forwardWhich graph represents f(x) = √x-2+3?arrow_forwardPractice Assignment 5.6 Rational Functions M Practice Assig Practice Assignment 5.6 Rational Functions Score: 120/150 Answered: 12/15 Question 10 A Write an equation for the function graphed below 5 + 4 1 2 H + + -7 -6 -5 -4 -3 -2 -1 2 34567 | -2 ర y = Question Help: Video Message instructor Post to forum Submit Questionarrow_forward
