Question

If the diameter of the circle below is 16 in., what is the area of the circle?

Answer 1

Answer:

64π inches² (approximately 201.06 inches²)

Step-by-step explanation:

$A=\pi r^2$ where $r$ is the radius

To find the radius, divide the diameter by 2

16 ÷ 2 = 8 inches

Plug in 8 as the radius

$A=\pi (8)^2\\A=64\pi$

$A=201.06$ (approximately)

Therefore, the area of the circle is 64π inches², or approximately 201.06 inches².

I hope this helps!

Answer 2

Answer:

201 inch²

Step-by-step explanation:

d=2r ⇔ 16=2r ⇔ r=8

A= Pi× r² ≈ 3.14 × 8² ≈ 201 inch²
