Find the volume v of the described solid s. a right circular cone with height 2h and base radius 5r step 1 we can form a cone of radius r and height h by rotating the region enclosed by the line y = r h x, the line x = h, and the x-axis about the x-axis. rotating a vertical strip between y = r h x and the x-axis around the x-axis creates a disk correct: your answer is correct. seenkey disk .

answer: i can’t tell you that

step-by-step explanation:

3.how is solving radical equations different than solving linear equations?

step-by-step explanation:

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.
