Suppose the manufacturer of light bulbs has two factories that make the same light bulb. NY AND NJ. A study is conducted in both factories on the number of hours the light bulbs last. Bulbs are tested based on random samples. Ny factory X= 500 hours and s= 8 hours, NJ Factory X=500 hours and s=20 hours

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base
