This question is a thought experiment.
It's essentially asking "Is 2πr² the same or not the same as π(2r)²?"
To figure it out, simply simplify π(2r)²
=π(2r)²
=π(2r)(2r)
=4πr²
Quite obviously, 2πr² is not the same as 4πr²
4+28= 32
Think of it as you have 28 apples and someone gave you 4 how many would you have
7/3=L/9
⇒63=3L
⇒L=21
which mean the Length equal 21 tiles and width equal 9 tiles for the new rectangle.
Answer:
14 Quarters and 28 dimes
Step-by-step explanation: 14 quarters $3.50
28 dimes is $2.80 total is $6.30
Answer:
0.9412
Step-by-step explanation:
Ultimately, if you know the length of the arc, and you know the length of the radius, the central angle (in radians) is just how many radii long the arc is. angle=arc lengthradius length=16 feet17 feet≈0.9412.
