Volume of a Rocket A rocket consists of a right circularcylinder of height 20 m surmounted by a cone whose heightand diameter are equal and whose radius is the same as thatof the cylindrical section. What should this radius be(rounded to two decimal places) if the total volume is to be500p/3 m3?
Question: Find the volume formed by rotating about the y-axis the region enclosed by:x = 10y ; y3 = x ; y (greater than or equal to) 0 My Comments: How do you find the bounds and which method would you use? The question doesn't specify which method and I'm also confused on which function to use for the height and which variable to use for the radius for the cylindrical shell method. (Assuming that is the right method to use.)
