Devin is asked to write out how to find the circumference of a circle. he writes:
"first measure the radius, then multiply that by 2, then multiply that answer by π, and that will give you the circumference."
which statement is another correct response?
a) first measure the radius then multiply that by π to find the circumference.
b) first measure the diameter then multiply that by π to find the circumference.
c) first measure the radius, then divide that by 2, then multiply that answer by π to find the circumference.
d) first measure the diameter, then divide that by 2, then multiply that answer by π to find the circumference.

Option B is correct

First measure the diameter then multiply that by π to find the circumference

Step-by-step explanation:

Circumference of a circle is given by:

or

where

C is the circumference of a circle

r is the radius of the circle

D is the diameter of a circle.

As per the statement:

He writes:

"First measure the radius, then multiply that by 2, then multiply that answer by π, and that will give you the circumference."

⇒

We know that:

Diameter of a circle(D) = 2r

then;

⇒First measure the diameter then multiply that by π, to get the circumference.

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
