747.7
d=14 we are looking for the radius divided it to half so it should be 7
the height is 10
A=2πrh+2πr2=2·π·7·10+2·π·72≈747.69905
When x=-4:
2(-4)+3y=4
3y=4+8
3y=12
y=4
So the ordered pair is (-4,4), I think
slope = m=(y2-y1)/(x2-x1)
m= (4-5)/(1-(-2))
m= -1/(1+2)
m=-1/3
Choice C
Answer:
9 hours
Step-by-step explanation:
$495 divided by 15 hours = $33 - this is how much the trainer charges per hour.
$297 divided by $33 per hour = 9 hours of training
Use arccos...cos^-1 so
cos^-1 (0.8195)
it equals 34.96522689°
