Answer:
(B) 9π in²
Step-by-step explanation:
I’m going to assume that by 6 inches you meant 6π inches.
If the circumference of a circle is 6π inches, then it’s radius will be half of 6 (because the circumference of a circle is
).

So the radius is 3.
Now that we know the radius, we can find the area by using the equation
.

Hope this helped!
Answer:
2/5 is tje correct answer for your question
Scarlet is leaning a 12 foot ladder. When you lean a 12 foot ladder, it is s slanted so we will make 12 our slanted side or hypotenuse. It makes a 80 degree angle after contact with the ground so it will be on the lowest angle on the right. We are asked to find the vertical side or how high up the ground is. We are asked to a angle that is opposite of the given angle which is x .. And we are also given the hypotenuse. We are going to use sin using our SOHCAHTOA

Where there is our given angle.
Let plug it in

Multiply 12 by both sides and we get

Which about 11.8 if rounded to nearest tenth or 11.82 if rounded to nearest hundredth.
IF ROUNDED TO NEAREST TENTH, 11.8
IF ROUNDED TO NEAREST HUNDRETH, 11.82
The slope of the line is -10.5.
Set it up as a proportion problem. $2.10 is to x pounds as $3.50 is to 1 pound
=$2.10/x pounds= $3.50/1 pound
Cross multiply
=($2.10 * 1)=($3.50 * x)
=2.10=3.50x
Divide both sides by 3.50
0.6= x
x= 0.6=6/10= 3/5
He can purchase 0.6 (or 3/5 in fraction terms) pounds for $2.10.
