I believe the radius would be 3.39

Hope this helps! Good luck! :)

<h2>Surface Area = 4πr²</h2>

144(π)cm² = 4(π)r² Divide by π on both sides

144cm² = 4r² Divide by 4 on both sides

36 = r² Find the square root of both sides

√36 = √r²

Find the exact value of each expression, if it defined. ( if answer is undefined, enter undefined) tan (-1)

Triss [41]

Answer:

$tan(-1) \approx -0.02$

Step-by-step explanation:

The given expression is

$tan(-1)$

The tangent of -1 is defined, it's around -0.02.

The tangent is a trigonometric function with a period of $\pi$ , where each period is separated by a vertical asymptote which indicates that the function is not determined through all its domain, that's what the question refers to when it says "if is undefined, enter undefined".

However, at $x=-1$ , the tangent is determined, that means, there's no asymptote on that coordinate, that's why it has a "determined value", which is -0.02 approximately.
