Answer:
No, they're not. To find the area of a circle you need to square the radius. They did not square the radius but instead multiplied it by 2.

Answer: 3 x 5
Step-by-step explanation: To find the prime factorization of 15, first create a factor tree with two branches. Since 15 ÷ 3 = 5, we know that 3 and 5 are factors of 15. So we write 3 and 5 at the bottom of the branches.
While 1 and 15 are also factors, we don't use them in out factor tree. That's because when finding the prime factorization, we always use numbers other than 1 and the number itself.
Next, we circle any prime factors in the factor tree. Since both 3 and 5 are prime, we circle both 3 and 5. Since we have circles at the bottom of all of our branches, we are finished.
So the prime factorization of 15 is 3 x 5.
Notice that we write our prime factorization as a multiplication problem. Think of the prime factorization of a number as the prime factors of the number that you multiply together to get the original number.

Amount = $400
Interest rate = 4% a year
----------------------------------------------------
Equation
----------------------------------------------------
Total amount = 400 + 0.04(400)
Total amount = 400 + 16
Total amount = $416
----------------------------------------------------
Answer: Total Amount = 400 + 0.04(400)

Answer: C 1*10^5
Step-by-step explanation:
There are 10^2 cm in a meter, and 10^3 meter in a kilometer, so there are 10^2 * 10^3 = 10^5 cm in a kilometer
Answer:
Step-by-step explanation:
Formula
t = 1.06 * p
Givens
p = 8.5
Solution
t = 1.06 * 8.5
t = 9.01
