Step-by-step explanation:
For a circular sector with a fixed perimeter of 100 ft, the values of radius (r) and arc length (s) that will maximize the sector's area are r=25 and s=50.
The perimeter of a circular sector is composed by the length of the arc (s) plus twice the radius (r). If this sum is fixed at 100 ft, then the length of the arc s is equal to 100 - 2r. The area A of a circular sector can be defined as A = 0.5 * r * s.
Substituting the expression for s into the area formula obtains A = 0.5 * r * (100-2r). Simplifying results in A = 50r - r^2 which is a downward opening parabola.
The maximum value of a parabola occurs at the vertex. For a parabola in the form y=ax^2 + bx + c, the x-coordinate of the vertex is -b/(2a). In this case, a=-1 and b=50, hence r=-50/2*(-1) = 25. Substituting r=25 back into the formula for s obtains s = 100-2*25 = 50. Therefore, the values for r and s that will give the circular sector the greatest area are r=25 and s=50.

The height of the cylinder is 7 centimeters. The volume and radius of the cylinder were used to find the height using the formula for the volume of a cylinder.
The formula for the volume of a cylinder is given by V = πr²h, where r is the radius and h is the height.
Substituting the given values, we get:
112 = π(4²)h
Simplifying:
112 = 16πh
Dividing both sides by 16π:
h = 112 / (16π)
Using a calculator to evaluate this expression, we get:
h ≈ 0.55 cm
Therefore, the height of the cylinder is approximately 0.55 centimeters.

Answer: 60 and 600
Step-by-step explanation:
The pattern is times 10
6x10=60 60x10=600
The number pattern multiplies each subsequent number by 10. Thus, the next two numbers in the sequence 0.006, 0.06, 0.6, and 6 are 60 and 600.
The question asked is related to a number pattern - specifically, it's about identifying the next two numbers in the series 0.006, 0.06, 0.6, and 6. Looking at this series, we can see a pattern: each subsequent number appears to be 10 times larger than its predecessor.
To get the next number in the series, we multiply the previous one by 10. So, if we multiply 6 by 10, we get 60. Therefore, 60 is the next number in the pattern.
Following this pattern, the number after 60 would be 10 times greater, which is 600. Therefore, the next two numbers in the series after 0.006, 0.06, 0.6, and 6 are 60 and 600.
