Solid of Revolution Consider the following integral, which calculates the volume of a cylinder by considering it as a solid of revolution: ∫2π0dϕ∫R0drhorhoh, where h is the height, rho is the integration variable of the radius from 0 to R, and ϕ is the integration variable of the angle from 0 to 2π. Solve this integral symbolically. Store your result in a variable volume, which should be a sympy expression. Use the variables names phi for

Step-by-step explanation:

In this case the solution of the integral is

because h is a constant, and where the expression

was used.

I hope this is usefull for you

regards.

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
