Answer:

A = 16pi

Step-by-step explanation:

The circumference of a circle is given by

C = 2 * pi *r

We are told the circumference is pi8

8pi = 2 * pi*r

Divide each side by 2pi

8pi/2pi = 2pir/2pi

4 =r

Now we want to find the area

A = pi r^2

A = pi(4)^2

A = 16pi

Ugo [173]

Answer:

D. 4 × 10⁶ times

Step-by-step explanation:

<u>The diameter of a pearl is </u>

4 × 10⁻³cm = 4 × 10⁻⁵ m

<u>The diameter of an atom is</u>

10⁻¹¹m

<u>How much larger than an atom is a pearl?</u>

4 × 10⁻⁵ ÷ 10⁻¹¹ = 4 × 10⁻⁵⁺¹¹ = 4 × 10⁶ times

Correct option is D
