Volume of the cone =

$\frac{1}{3}\pi r^2h$ $=\frac{1}{3}\times\pi\times3^2\times9=3^3\pi=27\pi\text{ square meters}$

Hi pls help.you do not have to do all 3. just either one will be ok pls explain as well:) thank you

Answer:

${7a^{5}b^{5} c\\$

Step-by-step explanation:

$\frac{28a^{8}b^{6} c^{3} }{4a^{3}bc^{2} }$

→ First look at the first term of each expression and see if they can be simplified, and they can

$\frac{7a^{8}b^{6} c^{3} }{a^{3}bc^{2} }$

→ Now look at the a terms, since a larger one is at the top, you subtract

$\frac{7a^{5}b^{6} c^{3} }{bc^{2} }$

→ Now simplify the b and c terms

${7a^{5}b^{5} c$

Substitute

4x+2=x-4

Then solve

3x=-6

x=-2

Substitute answer into an equation to find y

y=-2-4

y=-6

So you solution is:

Doug regularly mows his neighbor's lawn. Last month, Doug's neighbor paid him $55 for 6 hours of mowing. Is this situation most

nasty-shy [4]

Solution:

we are given that

Last month, Doug's neighbor paid him $55 for 6 hours of mowing.

we have been asked that

Is this situation most likely a proportional relationship?

yes..its as proportional relationship.

Because the amount that Doug get is $55 for 6 hours

It mean for each hour Doug get is $\frac{55}{6}$ $

It mean if you increase the number of hours then the number of dollars get paid also increases. Hence the given situation is most likely a proportional relationship.

Help pleaseeeeeee, I need help

Answer:

15, 60, and 61

Step-by-step explanation:

First we have to find the 3rd side length from 2 side length chosen. So let’s pick 8 meters and 11 meters, to find the third side length we use the Pythagorean theorem: c^2 = a^2 + b^2

c = 11^2 + 8^2 = 121 + 64 = 185 = 13.6

13.6 isn’t one of the answers so we can’t pick 11 & 8. Let’s try 11 & 15:

c = 15^2 + 11^2 = 225 + 121 = 346 = 18.6

18.6 isn’t one of the answers either. Let’s try 15 & 60:

c = 60^2 + 15^2 = 3600 + 225 = 3825 = 61.85

61.85 might be it but let’s try one more just in case:

c = 60^2 + 61^2 = 3600 + 3721 = 7321 = 85.6

Nope! That means 15, 60, and 61 are the answer. I hope this is correct!
