Suppose f(x)greater than0 for all x and integral from 0 to 4 f left parenthesis x right parenthesis dxequals22. let r be the region in the first quadrant bounded by the coordinates axes, yequalsf(xsquared), and xequals2. find the volume of the solid generated by revolving r around the y-axis.

1/2*qr*rs

step-by-step explanation:

tip $2.90

total $17.40

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.
