The area of a circle is 16π cm2. what is the circle's circumference?

Circumference of the circle is 25.12 cm

Step-by-step explanation:

We are Given: Area of the circle = 16π cm²

We need to find Circumference of the circle.

let r be the radius of the circle.

Then,

Area of the circle = πr²

πr² = 16π

r² = 16

r = √16

r = 4 cm

Now, Circumference of the circle = 2πr = 2 × 3.14 × 4 = 25.12 cm

Therefore, Circumference of the circle is 25.12 cm.

hope this is what you were asking for!

step-by-step explanation:

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
