Step-by-step explanation:

Formula:

$\boxed{a = 3.14(r)^{2} }$

r represents the radius.

The radius is 1/2 of the diameter.

Since 1/2 of 16 is 8, 8 is our radius.

Substitute:

$a = 3.14(8)^{2}$

Solve:

$a = 3.14(64)$

$a = 200.96in^{2}$

16:2 because that gives the radius
are of a circle= πr2
so you substitute in
r=8^2 =64
π=3.14
A=64x3.14
A=200.96

Point D is on line segment CE. Given CE=11 and CD=9, determine the length DE

Valentin [98]

11
•——-•——•
C D E
9 2
Because the line CE is 11, you will need to subtract it by 9 to find line DE.
11-9=2
To check your work you may add 9 and 2 to find out if it comes out to 11 and it does.
