Find the area of the figure given to the right. Round to the nearest whole number. 22 15 36 S The area of the figure is ft2​
Ede4ka [16]

Answer:

Step-by-step explanation:

Area of left rectangle:

Length = 36 ft

Width  = 8

Area1 = length * width

         = 36 * 8

        =  288 square feet

Area of right rectangle:

Length = 15 ft

Width = 22 - 8 = 14 ft

Area2 = 15 * 14

          = 210 square feet

Area of the figure = Area1 + area2

                            = 288 + 210

                            = 498 square feet

Find the area of the surface correct to four decimal places by expressing the area in terms of a single integral and using your
love history [14]

If we substitute x=r\cos\theta and y=r\sin\theta, we get r^2=x^2+y^2, so that

z=\cos(x^2+y^2)=\cos(r^2)

which is independent of \theta, which in turn means the surface can be treated like a surface of revolution.

Consider the function f(t)=\cos(t^2) defined over 0\le t\le1. Revolve the curve C described by f(t) about the line t=0. The area of the surface obtained in this way is then

\displaystyle2\pi\int_C\mathrm dS=2\pi\int_0^1\sqrt{1+f'(t)^2}\,\mathrm dt

=\displaystyle2\pi\int_0^1\sqrt{1+(-2t\sin(t^2))^2}\,\mathrm dt

=\displaystyle2\pi\int_0^1\sqrt{1+4t^2\sin^2(t^2)}\,\mathrm dt\approx7.4144
