4 0

Answer:

the radius must equal 2

Step-by-step explanation:

A = pi * r^2       C = 2 * pi *r

set them equal

pi * r^2 = 2 * pi *r

divide both sides by pi

r^2 = 2 * r

divide both sides by r

r^2 /r = 2r/r

r = 2

When the domain of a function has an infinite number of values, the range always has an infinite number of values. True or false
iragen [17]

Answer:

Thus, the statement is False!

Step-by-step explanation:

When the domain of a function has an infinite number of values, the range may not always have an infinite number of values.

For example:

Considering a function

f(x) = 5

Its domain is the set of all real numbers because it has an infinite number of possible domain values.

But, its range is a single number which is 5. Because the range of a constant function is a constant number.

Therefore, the statement ''When the domain of a function has an infinite number of values, the range always has an infinite number of values'' is FALSE.

Thus, the statement is False!
