2
Step-by-step explanation:
3-4+4+(-1) (-4+4=0)
=3-1
=2
Answer:
No
Step-by-step explanation:
Let's calculate sinA and sinB.
sinA = opposite / hypotenuse = 12 / 20
sinB = opposite / hypotenuse = 16 / 20
Since 12 / 20 ≠ 16 / 20, she is incorrect.
Answer:
14.13 m^2
Step-by-step explanation:
Formula for area:
3.14*r^2
To find the radius(r), you do diameter(d)/2:
9/2=4.5
3.14*4.5^2=14.13 m2
7.07 so I think you'd leave it at 7 for your answer
