Sketch the region of integration for the following integral. ∫π/40∫6/cos(θ)0f(r,θ)rdrdθ
solong [7]

Answer:

The graph is sketched by considering the integral. The graph is the region bounded by the origin, the line x = 6, the line y = x/6 and the x-axis.    

Step-by-step explanation:

We sketch the integral ∫π/40∫6/cos(θ)0f(r,θ)rdrdθ. We consider the inner integral which ranges from r = 0 to r = 6/cosθ. r = 0 is located at the origin and r = 6/cosθ is located on the line  x = 6 (since x = rcosθ here x= 6)extends radially outward from the origin. The outer integral ranges from θ = 0 to θ = π/4. This is a line from the origin that intersects the line x = 6 ( r = 6/cosθ) at y = 1 when θ = π/2 . The graph is the region bounded by the origin, the line x = 6, the line y = x/6 and the x-axis.

Find the base circumference of a cone with height 10 cm and volume 90π cm3 .
Leni [432]

Answer:

<em>Answer is </em><em>circumference</em><em> </em><em>=</em><em>32</em><em>.</em><em>64</em>

Step-by-step explanation:

given \\ volume \: of \: cone \:  = 90\pi \:  {cm}^{3}  \\ and \: height = 10 \: cm \:  \\ to \: find: circumference \\ by \: the \: given \: data \\ volume \: of \: cone = 90\pi \\  \frac{1}{3} \pi {r}^{2} h = 90\pi \\ cancelling \: \pi \: which \: is \: common \: \\ we \: get \\  \frac{1}{3 }  {r}^{2} h = 90 \\ we \: know \: that \: h = 10 \\ on \: substituting \: we \: get \\  \frac{1}{3}  {r}^{2}  \times 10 = 90 \\ dividing \: by \: 10 \: on \: both \: sides \: we \: get \\  \frac{1}{3}  {r}^{2}  = 9 \\  {r }^{2}  = 27 \\ r = 3 \sqrt{3}  \\ we \: know \: that \: circumference \:  = 2\pi \: r \\  = 2 \times  \frac{22}{7}  \times 3 \sqrt{3}  \\  on \: solving \: the \: above \: mentioned \: we \: get \\  \\  \:  = 32.64
