Answer:
We use formula, circumference=
to get r= 7.48
Step-by-step explanation:
Here is the complete question: The circumference of a pool is 47 feet. Which formula can you use to find Radius (r), if you know that C =2πr.
Given: Circumference= 47 feet.
We will use formula of circumference to find radius (r) as given.
Circumference = 
⇒
(∵ we know π=3.14)
Cross multiplying both side to get r.
⇒ r= 
∴ radius (r)= 7.48
∴ We will use circumference formula
to find Radius (r).
2mn - 3m + 8n - 12
Let's group the first two terms together and the last two:
2mn - 3m and 8n - 12
In the first group, m is the greatest common factor.
m(2n - 3)
In the second group, 4 is the greatest common factor.
4(2n - 3)
Therefore, (m + 4) and (2n - 3) are our factors. Our missing term is 2n.

Given:
Volume of cube = 140.608 cubic millimetres
Step-by-step explanation:
Let the length of each side of cube = a

Therefore length of each side of cube = 5.2 mm
