Answer:
As a triangle because it's a quadratic shape
The circumference of any circle is (pi) x (the diameter of the circle).
The problem gives you both numbers, so all you have to do is multiply them.
Circumference = (pi) x (diameter) = (3.14) x (21cm) = <em>65.94 cm .</em>
The answer is 60 surprisingly
Answer:
The second amount is 3.72
Step-by-step explanation:
Given


Required
Find Second

Substitute 9.92 for First

Express as fraction

Multiply both sides by 9.92



If x to the 12th power is divided by x to the 9th power:
Since they share same bases, and are being divided, it would be the same as x^{12 - 9), or x^{3}
Now, simply find the cube root of 125, which is 5.
Therefore, the number (x) must be equal to 5.
