Answer:
3
Step-by-step explanation:
I am not quite sure what the question asks for,
But this is what i assume it wants:
Cos A= 0.6489
In this given one, we basically find the size of the angle A
we do cosine inverse on both sides to get the size of the angle A

: It looks like this in the calculator

× cos A=

(0.6489)
(

and cos cancels out)
A=

(0.6489)
A=49.54°
check:
cos 49.54=0.6489 (its right!)
Formula for the volume not a cone=πr2H. π=3.14. R=12×2=24. H=16. 3.14×24=75.36. 75.36×16=1205.76. ANSWER: 1205.76
Answer:
50,000 + 3,000 + 200 + 70 + 4
Step-by-step explanation:
Expand. Set all non-zero digits by itself:
53,274 = 50,000 + 3,000 + 200 + 70 + 4
Remember to fill in 0 for all digits. They must keep their value.
