Answer:
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.
