What is the volume of the cone to the nearest tenth?
401.2 yd?
421.4 yd
484.3 yd?
536.2 yd

536.2 yd^2

Step-by-step explanation:

volume of the cone is equal to

1/3 π r^2h {here h is height of cone & r is radius}

i.e, 1/3 ×π × (8yd)^2 × 8yd

= 536.16 yd^2

≈536.2 yd^2

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.
