Answer: 26.8
Step-by-step explanation:
4.5x6.4=28.8m
1.2x0.6=0.72m
1.6x0.8=1.28m
0.72+1.28=2m
28.8-2=26.8
C = 2πr
17 = 2(3.14)(r)
17 = 2(3.14r)
17 = 6.28r
6.28 6.28
2.71 ≈ r
Answer:
Step-by-step explanation:
For two matrix P and Q, the product, say PQ is defined when:
The number of columns of P = The number of rows of Q
Since A is a 2×2 matrix and B is also a 2×2 matrix
Thus both AB and BA are possible.
So AB is:
BA is:
