A circular room of radius 14 m is to be covered by a square carpet. What will be the maximum area the carpet can cover? If the same area is to be paved with square tiles with a side length of 70 cm, then how many tiles would be needed?

sad to say that idont know

1256.63 tiles

Step-by-step explanation:

the question is not quite clear but I assume that it is asking how many tiles of length 70cm is required in order to pave the circular area.

Given,

radius(r) = 14m= 1400cm

Area of the circle= πr²= π×1400²= 6157521.6 cm²=

length of square tile(l)= 70cm

area of square= l²= 70×70= 4900cm²

now,

number of tiles required= area of circle ÷ area of tile

= 6157521.6 ÷ 4900= 1256.63 tiles

Hope this helps.

irrational, cannot

the answer is a if my teacher taught me correct
