Answer:

sqrt(A /pi ) = r

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

Divide each side by pi

A / pi = r^2

Take the square root of each side

sqrt(A /pi ) = sqrt(r^2)

sqrt(A /pi ) = r

If the function 5x+y=1 has the domain (-2,1,6) then what is the corresponding range?
zysi [14]

The corresponding range of the domain is (11, -4, -29)

<h3>How to determine the range?</h3>

The function is given as:

5x + y = 1

Make y the subject

y = 1 - 5x

The domain is given as:

(-2,1,6)

Substitute these values in y = 1 - 5x

y = 1 - 5(-2) = 11

y = 1 - 5(1) = -4

y = 1 - 5(6) = -29

Hence, the corresponding range of the domain is (11, -4, -29)
