Which expression can be used to find the volume of the cylinder in this composite figure?
Whitepunk [10]

Answer:

The volume of the cylinder is 112\pi\ cm^{3}

Step-by-step explanation:

we know that

The volume of the cylinder is equal to

V=Bh

where

B is the area of the base

h is the height of the prism

B=\pi r^{2}

In this problem we have

r=4\ cm

h=7\ cm

substitute

Find the area of the base B

B=\pi (4^{2})

B=16\pi\ cm^{2}

substitute in the formula of the volume

V=16\pi (7)

V=112\pi\ cm^{3}

Help me please I'm stuck! With the first column
frosja888 [35]
1. \frac{n}{4}

2. -2+5n or 5n-2

3. (12s)+150 where s=number of students

4. 3(32)+1(53)=96+53=159 per hour, so 159h

9. √105 is irrational, -4 is an integer, 4/3 is a rational number, order is -4,3/4, √105

10. 3²=9, 4²=16, so between 3 and 4, but closer to 4, so √14≈4

11. that is the associative property, it deals with moving parentahees around

12. 2(6.25)+1(5.50)+2(2.75)=2(6.25+2.75)+1(5.50)=2(9)+5.5=18+5.5=23.5

13. yes, because they are both 2 less than 3 times of a number

14. maybe 18 times 3, so (4²+2) times 3=54
