Point B is the center of the circle shown, and the length of arc AC is 8π. What is the area of the circle?
Answer:
[tex]A=324\pi \text{ units}^2\approx1017.88\text{ units}^2[/tex]
Step-by-step explanation:
The formula for arc length is:
[tex]\stackrel{\frown}{A}=2\pi r(\frac{\theta}{360}})[/tex]
Where Θ is measured in degrees.
We know that the arc length is 8π when the degree is 80. So, substitute 8π for A and 80 for Θ:
[tex]8\pi=2\pi r(\frac{80}{360})[/tex]
Divide both sides by 2π:
[tex]4=r\frac{80}{360}[/tex]
Simplify the fraction:
[tex]4=\frac{2}{9}r[/tex]
Multiply both sides by 9/2:
[tex]r=18[/tex]
So, the radius is 18.
Now, we can find the area of the circle. The formula for the area of a circle is:
[tex]A=\pi r^2[/tex]
Substitute 18 into r:
[tex]A=\pi (18)^2[/tex]
Simplify:
[tex]A=324\pi \text{ units}^2\approx1017.88\text{ units}^2[/tex]
And we're done!

A

WELP WILL MARK BRAINLEST 4. Part A: Jerry claimed that the expression -8 + d is negative. Determine whether Jerry's claim is always true, sometimes true, or never true. Provide evidence to support your conclusion. (10 points)
Answer: His claim is SOMETIMES true.
Let's just take an example, d=2.
-8 + 2 equals -6, so negative. BUT, let's say d=9.
-8 + 9 equals 1, 1 is positive.
Jerry's claim is sometimes true.

Which equation demonstrates the distributive property?
do you want me to explain what the distributive property is????
i'm confused-
Answer:
The distributive property of multiplication states that a ( b + c ) = a b + a c . It's often used for equations when the terms within the parentheses can't be simplified because they contain one or more variables.

10 ( x 2 + 6 ) = 8
Multiply out the bracket
5 x + 60 = 8 Subtract 60 from both sides 5 x = 58
Divide both sides by 5 x = 58 5
10 times: Subtract 60 from both sides
5 x = 58 Divide both sides by 5 x = 58 5
