1 and 3 only answer is number 2
Circumference of a circle =
(diameter)
Diameter = 23 in.
Plug in the diameter = 23 in in the formula of circumference given above
Circumference of a circle =
(23)
Circumference of a circle = 23
= 3.14
Circumference of a circle = 23 (3.14)
Circumference of a circle = 72.22 in

Hello! Remember you have to write clear questions in order to get good and exact answers. Here, I'll assume the function as:

The y-intercept of a function is the point at which the graph of the function touches the y-axis. This occurs when we set
. In other words, we define the y-intercept (let's call it
as:

Setting
in our function we have:

So <em>in this context the y-intercept is -16</em>
To find the area you do A=bh(basexheight) 12x8=96
Answer:
∠7=22°
Step-by-step explanation:
∠2 and ∠7 are supplementary angles, meaning they add to 90°.
∠2+∠7=90°
substitute ∠2
68°+∠7=90°
∠7=22°
