satellite73 (satellite73):

\[360\div 60=6\] you have one sixths of the total area

OpenStudy (rootbeer003):

so b

satellite73 (satellite73):

no what is \(42\div6\)?

OpenStudy (rootbeer003):

7

satellite73 (satellite73):

right

OpenStudy (rootbeer003):

satellite73 (satellite73):

\[\checkmark\]

OpenStudy (rootbeer003):

satellite73 (satellite73):

\[\checkmark\]

OpenStudy (rootbeer003):

satellite73 (satellite73):

idk multiply by 6, see what you get

OpenStudy (rootbeer003):

i got 1203

satellite73 (satellite73):

really?

OpenStudy (rootbeer003):

no.

satellite73 (satellite73):

\[7.5\times 6=1203\] new math

OpenStudy (rootbeer003):

satellite73 (satellite73):

\[\checkmark\]

OpenStudy (rootbeer003):

satellite73 (satellite73):

\[\checkmark\]

OpenStudy (rootbeer003):

satellite73 (satellite73):

guess

OpenStudy (rootbeer003):

d

satellite73 (satellite73):

heck no

OpenStudy (rootbeer003):

10

satellite73 (satellite73):

use pythagoras \[a^2+b^2=c^2\\ 6^2+8^2=c^2\]

satellite73 (satellite73):

\[36+64=c^2\\ 100=c^2\] yeah \(10\)

OpenStudy (rootbeer003):

satellite73 (satellite73):

not clear what is 14 in that picture

satellite73 (satellite73):

but if it is the entire base, then you are right \[\frac{14+6}{2}\times 6=60\]

OpenStudy (rootbeer003):

satellite73 (satellite73):

oh no

satellite73 (satellite73):

\(\pi r^2\) in your case \(r=6\)

OpenStudy (rootbeer003):

a

satellite73 (satellite73):

you guessing? what is \(6^2\)?

OpenStudy (rootbeer003):

36

OpenStudy (rootbeer003):

satellite73 (satellite73):

\[\checkmark\]

OpenStudy (rootbeer003):

satellite73 (satellite73):

\[3,4,5\] is a right triangle since \[3^2+4^2=5^2\] multiply all sides by 3, get \(9,12,15\)

OpenStudy (rootbeer003):

soo im right?

satellite73 (satellite73):

i didn't see an answer but "right" is right

OpenStudy (rootbeer003):

hah

OpenStudy (rootbeer003):

satellite73 (satellite73):

\[a^2+b^2=c^2\\ x^2+24^2=30^2\\ x=\sqrt{30^2-24^2}\] and a calculator

satellite73 (satellite73):

or, another 3, 4, 5 right triangle \[6\times 5=30,6\times 4=24, 6\times 3=?\]

OpenStudy (rootbeer003):

18

OpenStudy (rootbeer003):

satellite73 (satellite73):

yet another 3 - 4 - 5 \[4\times 3=12,4\times 4=16, 4\times 5=?\]

OpenStudy (rootbeer003):

20

satellite73 (satellite73):

bingo

OpenStudy (rootbeer003):

ok bye

satellite73 (satellite73):

k bye
