A cylindrical vase has a diameter of 4 inches. At the bottom of the vase, there are 6 marbles,
each of diameter 3 inches. The vase is filled with
water up to a height of 8 inches.
Which of the following could be used to calculate
the volume of water in the vase? (6 points)
n(2in)2(8in) - 60 n(1.5in)3)
O
n(8in)?(2in) – 60 (1.5in)3)
О
n(2in)?(8in) – 1.50 (6in))
4
(8in)2(2in) – 1.50
n(6in)3)
3

A or π(2in)2(8in) − 6(four over threeπ(1.5in)3)

Explanation:

First you need to know the volume of a cylinder which is V= π r^2h

Then you plug the question into the volume equation giving us V = 3.14*(2^2)*8

(the radius is 2 because the diameter (4) can be split in half)

The only ones matching that explanation is A and C

Finally A is the answer because the 6 marbles were mentioned first so that gives us A

also i took the quiz and got it right :)

the industrial development of cities in the ruhr area in the nineteenth century is described. the research was based on english and german language sources. several factors that shaped growth and paths of the cities were categorized and analyzed. they are locations, resources, traditions, entrepreneurs, and technological developments. locations and resources were the most important among them; other factors may be regarded as consequences from locations and resources. among the cities, bochum, essen, gelsenkirchen, and dortmund had the richest resources and most favorable locations in the transportation network and grew to be the largest cities in the ruhr area near the end of the nineteenth century. riverside location was also a favorable factor for the development, as shown in the development of duisburg on the confluence of rhine and ruhr. resource distribution can explain the rise of textile industry, metallurgical industry, and coal and iron industries, and the northward progression of the mining industry. tradition was an important factor for cities such as krefeld, barmen, elberfeld, solingen, and remscheid, which experienced development based on their traditions through the nineteenth century. various entrepreneurs exerted influences within and beyond the local level over the ruhr area. technological development stimulated the northward progression of the mining industry and the deep connection between the coal and the iron industries.
