Answer:
$48.60
Step-by-step explanation:
4 7/5 can be expressed differently... but anyway..... this is how I got it.
5/6 kg ------> cost $7.50
1 kg ----> costs $7.50 ÷ 5/6 kg = $9
4 7/5 kg ------> costs $9 x (4 7/5) = $9 x (27/5) = $48.60
Area = πr² ⇒
81π = πr² ⇒ 81 = r² ⇒ r = √81 = 9 in
<span>Circumference = 2</span>πr = 2*9*π = 18π in
Coplanar lines are the lines in the same plane and as parallel lines are always in same planes, it would be always coplanar.
In short, Your Answer would be Option A) Always
Hope this helps!
