Answer:
3pi or approximately 9.42
Step-by-step explanation:
The diameter is 3
The circumference is given by
C = pi *d
C =3 pi
We can approximate pi by 3.14
C = 3*3.14
C =9.42
We calculate the floor area of the kitchen:
A = (22) * (16)
A = 352 feet ^ 2
We consider the following conversion:
1 foot = 12 inches.
Applying the conversion we have:
A = 352 * (12/1) ^ 2
A = 50688 in ^ 2
We calculate the area of each tile:
A = (16) * (16)
A = 256 in ^ 2
Then, the number of tiles is given by:
N = (50688) / (256)
N = 198
Answer:
He needs to buy 198 tiles
Yes, it is a rhombus because the diagonals are congruent.
