Step-by-step explanation:
Multiply the radius by 2 to get the diameter. Multiply the result by π, or 3.14 for an estimation. That's it; you found the circumference of the circle
And then for diameter you have to Multiply the diameter by π, or 3.14. The result is the circle's circumference.
The 4 on the left side is 10x more than the 4 on the right. This only works if the numbers are next to each other and are the same.
What is the question? I don't understand your question.
<u>Define x and y:</u>
Let the first number be x and the second number be y.
<u>Setup the equations:</u>
y + 2x = 10 ----------- (1)
2y + x = 11 ----------- (2)
<u>Solve x;</u>
From (1):
y + 2x = 10
y = 10 - 2x ----------- Sub into (2)
2(10 - 2x) + x = 11
20 - 4x + x = 11
20 - 3x = 11
3x = 20 - 11
3x = 9
x = 3 ----------- Sub into (1)
y + 2(3) = 10
y = 10 - 6
y = 4
<u>Find the numbers:</u>
First number = x = 3
Second number = y = 4
Answer: The two numbers are 3 and 4.
