Imagine that plaque uniformly coats the walls of the blood vessel in the diagram. Based on the diagram, what is the reduced area inside the blood vessel? Round your answer to the nearest tenth. The equation for the area of a circle is A = πr2, where A is area, π ≠3. 14, and r is the radius. Recall that the radius is half of the diameter.

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.

it would be a on edgenuit y

the diagram below is your final answer

the answer to this in exact form is 4/35 but in decimal form its 0.1142857

hope this if needed hmu
