1) -0.4
2) 3
3) -37
For each I just subsitubed
1) 3(1.2)-4
3.6-4 = -0.4
2) 12-(9)=3
3) 4(2)-45
8-45=-37
Answer:
1442 (nearest whole number)
Step-by-step explanation:
The volume of a cone is given by
We are given both the radius (r) and height (h). Sub these values into their respective variables,
Put this into the calculator and you will get V = 1441.9910....
Rounding this to the nearest whole number would be 1442
Hope this helped!!
The answer is the second choice

your just gonna multiply 13x3 to get your answer
Hope this helped :D
Answer:
(1 + √2)/2
Step-by-step explanation:
Assuming the values are in degrees,
sin(45) = sin(π/4)=√2/2
cos(60) = cos(π/3)=1/2
thus
sin(45) + cos(60) = √2/2 + 1/2 = (1 +√2)/2
