8. In the cone below A is 3 cm. C is double length of A. What is the
total volume of the cone?
F. 18 cm
G. 36 cm
H. 57 cm
1. 85 cm
VOLUME

The volume of the cone is 57 cm³.

Solution:

Given data:

A = Radius of the cone (r) = 3 cm

C = Height of the cone (h)

   = Double length of A

   = 2 × 3 cm

C = 6 cm

The value of π = 3.14

Volume of the cone:

cm³

Round to the whole number, we get

V = 57 cm³

The volume of the cone is 57 cm³.

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.
