First let's review the area formula for a circle.
Area=π
Now that we know the radius, r is 10. The area is
10*10*π=100π
I will approximate π to 3.14 although you could do it more precise or less precise. The final answer will be 100*3.14=314 squared centimeter.

Answer:
9t + 3s = 420
t + 6s = 296
s =44; t = 32
Step-by-step explanation:
Let
Price of a T-shirt = t
Price of a sweatshirt = s
Jayden:
9t + 3s = 420
Carson:
t + 6s = 296
9t + 3s = 420 (1)
t + 6s = 296 (2)
From (2)
t =296 - 6s
Substitute t =296 - 6s into (1)
9t + 3s = 420 (1)
9(296 - 6s) + 3s = 420
2664 - 54s + 3s = 420
2,664 - 51s = 420
-51s = 420 - 2,664
-51s = -2,244
s = 44
Substitute s = 44 into (2)
t + 6s = 296
t + 6(44) = 296
t + 264 = 296
t = 296 - 264
t = 32
s =44; t = 32
Answer:
A counterexample is sufficient, as long as it is well built and complete.
Step-by-step explanation:
A counterexample is a statement used to show that a previously spoken statement is false.
The counterexample must be direct, clear, simple, well constructed and concise to be effective. If the counterexample has all of these characteristics, only one counterexample is sufficient to show that a conditional statement is flawed.
As an example of this, we can use a square as a counterexample of a statement that states that every rectangle has 4 equal sides.
