Answer:
A=103.13cm
Step-by-step explanation:
Formula: A= c^2/4π (C being the circumference and ^2 means it's squared)
Plug in what you know: 36^2/4π
1296/4π= 103.13
1.33333333333 is the answer
Answer: option a.
Step-by-step explanation:
Given the expression
, you need to remember:
The Product of powers property:

The Power of a power property:

And:
![\sqrt[n]{a^n}=a](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%5En%7D%3Da)
Therefore, as the index of the radical is 2, you can rewrite
as:

Rewrite this and simplify. Then:


This matches with the option a.
