If the radius of the circle above is 12 in, what is the area of the circle? A. 576 sq in B. 144 sq in C. 12 sq in D. 24 sq in

Step-by-step explanation:

Formula for the area of a circle of radius r is A = πr², where r is the radius.

Here, A = π(12 in)²  = 144π in², or approximately  452.89 in².

Double check to ensure that you have copied down the possible answers correctly.  Answer B would be correct if you were to insert π.  (See above.)

no he doesnt because "-16' is negatiive

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
