What is the exact area of a circle with a radius of 12 ft

lisov135 [29]

Answer:

The area is approximately 453 ft²

Step-by-step explanation:

Area of a circle = $\pi r^{2}$

If $\pi$ = 22/7, and r = 12 ft

Area = (22/7)×12²

= 3.143*144

= 452.592 ft²

≈ 453 ft²

Let f(x) = √x-5<br><br> Find f^ -1.

iris [78.8K]

Answer:

$f^{-1}(x)= x^2 + 5 \,,\,\,x\geq 0$

Step-by-step explanation:

Use the method of swapping x and y and isolating y.

$f(x) = y = \sqrt{x-5}\,,\,\,\,x\geq 5,y\geq0\\\\f^{-1}:x=\sqrt{y-5}\,,\,\,\,y\geq 5, x\geq 0\\x^2 = y-5\\y = x^2 + 5 = f^{-1}(x)\\$

Note that domain/range will be swapped as well.
