Area of a circle is the region occupied by the circle in a two-dimensional plane. It can be determined easily using a formula, A = πr2

, (Pi r-squared) where r is the radius of

the circle. The unit of area is the square unit, such as m2

, cm2

, etc. Non- routine

problems typically do not have an immediately apparent strategy for solving them. While

in routine problem it can be solve by using formulas, symbols, and operation.​

explanation:

a .4y4

hope this !

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
