Answer 8

oh yeah i randomly clicked that tbh i was getting frustrated

Answer 9

whereas a and b is the height and the radius and c is the slant height

Answer 10

so the first one... you plug the numbers in
\(9^2+4^2=c^2\)

Answer 11

i did 8^2+9^2 and got 145
and then i divided that in half so i got 72.5

Answer 12

u will find it not a perfect square tho

Answer 13

i don't get u wht did u get as the answer tho?

Answer 57

im lost tbh

Answer 58

here hang on i think they gave us instructions

Answer 59

... let's see...

116 / 2 = 58 = x
right

Answer 65

no...

Answer 66

the square root! not divided by 2!

Answer 67

no u square root it not divide it by 2

Answer 68

its \(\sqrt116\)

Answer 69

sorry lmao my brain is being dumb i knew i was doing that wrong

Answer 70

\(\sqrt{116}\)

Answer 71

not 116 \(\div\) 2!!

Answer 72

10.7

Answer 73

jeez he got it

Answer 74

so its about... 11

Answer 75

round it!! don't make it harder!! make it easier so its 11

Answer 76

ty u guys

Answer 77

now solve this
\(11^2+10^2=c^2\)

Answer 78

well its multiple choice and im supposed to round it to the nearest tenth so 10.77 would be 10.8 there isnt even an option for 11

Answer 79

221=\(c^2\)

Answer 80

no it's not done yet... u found the diagonal of the BASE not the RECTANGULAR PRISM

Answer 81

14.86
oh okay

Answer 82

:Dnex t question

Answer 83

=-= 15!

Answer 84

:P

Answer 86

u gtta ROUNDD welll..... true... but then.... D: I WANNA ROUND IT

Answer 87

now for the enxt problem...
solve this:
\(14^2+3^2=c^2\)

Answer 88

205=\(c^2\)

Answer 89

somewhere around 14. so now solve this:
\(14^2+4^2=c^2\)

Answer 90

and then u can get ur answer

Answer 91

14.31?

Answer 92

i think it should be a bit more than that

Answer 93

through mental math, i figured that it should be 14.8
