Answer:

201 inch²

Explanation:

d=2r ⇔ 16=2r ⇔ r=8

A= Pi× r² ≈ 3.14 × 8² ≈ 201 inch²

Answer:

64π inches² (approximately 201.06 inches²)

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!
