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:

201 inch²

Step-by-step explanation:

d=2r ⇔ 16=2r ⇔ r=8

A= Pi× r² ≈ 3.14 × 8² ≈ 201 inch²

Ignore above
your equation is 2(cosx)^2-3cosx+1=0
use quadratic formula to get results
you will end up with
cosx=1 or cosx=1/2
so, x=0 or x=pi/3

melamori03 [73]

The biggest number of groups that can be formed is 6, because six is the greatest common factor of 12 and 42. There will be 2 coaches in each group because 6 x 2 = 12 and 7 players in each group because 7 x 6 = 42.
