The circumference of a circle is 20(pi) ft. What's the area of the circle?

A=31.75cm

Step-by-step explanation:

First find the Radius

c=2Πr=20

2(3.14)r=20

6.28r=20

6.28r/6.28=20

r=20/6.28

r=3.18

from here then you can able find the Area of the cycle

A=Πr^2

A=3.14×3.18^2

A=31.75cm

answer: c. is your answer

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.
