Answer:
196000 tiles.
Step-by-step explanation:
The 28 m is 2800 cm. So a 28 x 28 meter square would be 2800 x 2800 centimeter square.
The tiles are 40 cm.
If you divide 40 from (2800 x 2800). (2800 x 2800) ÷40 = 196000
So 196000 tiles.
I'm not entirely sure if that's correct, but if it helps that's awesome.
Yes, you can use division to solve a missing factor problem
Volume of a pyramid is 1/3 base x height or 1/3 b h ( rest are in the Comments
The diameters intersect at the center of the circle
m<BKD = 100
<AKC is vertical to <BKD, so m<AKC = 100
An arc has the same measure as its central angle,
so m(arc)AC = 100
