Irrational
We know that pi is irrational (we can’t express it as a ratio of two numbers), and we are multiplying it by a rational number (-2). However -2 lots of something with infinite digits, will still have infinite digits, therefore it is irrational.
Answer:
C / (2 pi) = r
Step-by-step explanation:
C = 2 pi r
Divide each side by 2 pi
C / (2 pi) = 2 pi r/ (2 pi)
C / (2 pi) = r
1 yard = 36 inches. We have 5 yards, so 5x36 = 180
1 foot = 12 inches.
So the base 192 is largest.
Answer:
Step-by-step explanation:
If the radius, r, is given, then the area of the circle is A = πr².
If the diameter, d, is given, then the circle area is A = π(d/2)², or A = πd² / 4.
