C=2pir
area=pir^2
given
c=25.12
25.12=2pir
pi=3.14
25.12=2(3.14)r
25.12=6.28r
divide both sides by 6.25
4=r
sub into other
area=pir^2
area=pi4^2
area=16pi
area=16(3.14)
area=50.24
the area is 50.24 square cm
Step-by-step explanation:


Answer:


Step-by-step explanation:
Given


Required
- Convert 6 lb to kg
- Convert 11kg to lb
To solve for (a), we make use of the second conversion unit:

Multiply both sides by 6


<em>Hence, a 6lb backpack weighs 2.724kg</em>
Solving (b): 11 kg to lb
Here, we make use of the first conversion unit

Multiply both sides by 11


<em>Hence, the cat weighs 24.2lb</em>

ANSWER:
B. $3.50
STEP BY STEP EXPLANATION:
We start out with buying the stock for $15.75 then sell it at $19.25. We need to find the difference.
Subtract $15.75 from $19.25
19.25 - 15.75 = 3.50
To check your work add $3.50 to $15.75
15.75 + 3.50 = 19.25
