Answer:
4pi
Step-by-step explanation:
Area of a circle is pi (r^2)
Radius is 2, 2 squared is 4, 4 times pi is 4pi.
Answer:
x= 
Step-by-step explanation:
We have given,

We need to solve for x.

Squaring both sides, we get:
3-5x = x + 2
or 3 - 2 = x + 5x
or 1 = 6x
or x = 
Hence we got x= 
only integers and polynomials are under subtraction.

- [Equality Property] Square root both sides:

Since the quotient of the two decimal numbers is 1, that tells use that they are the same number.
Since the sum of the two numbers equals 1 and both numbers are the same, then the answer must be 1 divided by 2. or .5
the fractions would be 1/2 and 1/2
