The circumference of a circle of diameter 10 cm is _____.A
3.14 cm
B
0.314 cm
C
314 cm
D
31.4 cm

Answers

Answer 1
Answer:

For a circle with a diameter of 10 cm, the circumference would be C = π(10) = 31.4 cm. The correct option is (D) 31.4 cm.


The circumference of a circle can be calculated using the formula           C = πd, where C represents the circumference and d represents the diameter of the circle.

We have the diameter of the circle is 10 cm, we can substitute this value into the formula:

C = π * 10 cm

Calculating the circumference using an approximate value of π as 3.14:

C ≈ 3.14 * 10 cm

C ≈ 31.4 cm

Therefore, the circumference of a circle with a diameter of 10 cm is approximately 31.4 cm.

The correct answer is D) 31.4 cm.

Answers

The correct answer is 45. The rule to the numbers is x + 9 and then x + 2.

12 + 9 = 21
21 + 2 = 23
23 + 9 = 32
32 + 2 = 34
34 + 9 = 43
43 + 2 = 45

Peggy had four times as many quarters as nickels. She had $2.10 in all. How many nickels and how many quarters did she have?Which of the following equations could be used to solve the problem?

Answers

value of the coin times number of coins summed up equal total value
so since we have "$2.10 in all"...
0.05n + 0.25q = 2.10

and we are told that there are "four times as many quarters as nickels"
this translates to
q = 4n

0.05n + 0.25q = 2.10
and
q = 4n
are your two equations that could be used to solve this problem


if you would like to know how many nickels and how many quarters there are, plug in q = 4n into the first equation and get
0.05n + 0.25(4n) = 2.10

multiply
0.05n + 1n = 2.10

add like terms
1.05n = 2.10

divide both sides by 1.05
n = 2.10/1.05 = 2

then plug that back into
q = 4n
so
q = 4(2) = 8

therefore you have 
2 nickels
and
8 quarters
