<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

<h2>6 = r</h2>

Answer:

B<C

Step-by-step explanation:

-a is the opposite of a. Since a is a negative number, it will become positive and be bigger than b, which is negative.

c is a positive number, so the opposite will be negative and can not be bigger than c.

Hoochie [10]

it would take Janis 14 minutes to complete a package alone

<h3>How to determine the value</h3>

From the information given,

Let's say that

Carol working time = x = 30 minutes

Janis working time = y

x + y = 16 minutes

Let's make 'y' the subject

30 - 16 = y

y= 14 minutes

Thus, it would take Janis 14 minutes to complete a package alone
