A, tell me if wrong. Also if it it wrong i am really sorry
AC = 9 m; BC = 16.16 m; BD = 28.27 m; CD = 12.12 m
<em>Find AC
</em>
AC = AB = 9 m
<em>Find BC</em>
∠BAC = 2π – 10π/7 = (14π – 10π)/7 = 4π/7
BC = <em>θr</em> = 4π/7 × 9 m = 16.16 m
<em>Find BD
</em>
∠BAD = π
BD = <em>θr</em> = π × 9 m = 28.27 m
<em>Find CD</em>
<em>C</em> = 2π<em>r
</em>
CD = <em>C</em> – BC – BD = 2π<em>r</em> – 4π<em>r</em>/7 – π<em>r</em> = (14π<em>r</em> – 4π<em>r</em> – 7π<em>r</em>)/7 = (3π/7)<em>r</em>
= (3π/7) ×9 m = 12.12 m
(12 2/3)*(3 1/4) = 41 1/6 . . . . . according to my calculator

You are usually taught to multiply the improper fractions and simplify the result.
.. (38/3)*(13/4) = (38/4)*(13/3)
.. = (19/2)*(13/3)
.. = (19*13)/6
.. = 247/6
.. = 41 1/6
You can also multiply the parts.
.. (12 2/3)*(3 1/4) = 12*3 + 12*(1/4) +(2/3)*3 +(2/3)*(1/4)
.. = 36 +3 +2 +1/6
.. = 41 1/6
Answer:
-7 degrees Celsius
Step-by-step explanation:
You subtract 25 by 32 and get -7 degrees.
Answer:
around 1800 full rotations
Step-by-step explanation:
a circle is 360 degrees so if the bug was on it for 5 rotations then it would have traveled 360x5
