Answer:
17.8 cm³
Step-by-step explanation:
The radius of the roll is half the diameter, so is 9 mm. The length of the roll of 50 dimes is 1.4·50 mm = 70 mm. With these dimensions, we can use the formula for the volume of a cylinder:
V = πr²h = π(9 mm)²(70 mm) = 5670π mm³ ≈ 17,812.8 mm³
Perhaps a more convenient unit of measure is cm³. Each cm³ is 1000 mm³, so the volume of a roll of dimes is approximately ...
V ≈ 17.8 cm³
Answer:
answer is (d) 4/3
Step-by-step explanation:
-x+3/7=2x-25/7
25/7+3/7=2x+x
28/7=3x
4=3x
x=4/3
Answer:
Horizontal
Step-by-step explanation:
The x-axis is horizontal while the y-axis is vertical.
I'll assume you're supposed to compute the line integral of over the given path . By the fundamental theorem of calculus,
so evaluating the integral is as simple as evaluting at the endpoints of . But first we need to determine given its gradient.
We have
Differentiating with respect to gives
and we end up with
for some constant . Then the value of the line integral is .
