So the circumference of a circle is C=2 times pi times the radius. in this case it would be C= 2(pi)(4) which is 25.1 :)

<h2><u>Problem</u>:-</h2>

Find the perimeter or circumference and area of each figure. Round to the nearest tenth.

<h2><u>Solution</u>:-</h2>

The circumference of a circle with radius r is given by C = 2πr. The radius of the circle is 4 in.

Substitute 4 for r.

\sf{C=2πr}

\sf{ \:  \:  \:  \: =2π(4)}

\sf{ \:  \:  \:  \: ≈{\color{darkviolet}{25.1}}}

<h3><u>Answer</u>:-</h3>

The circumference of the circle is about 25.1 in.

<h2>======================</h2>

The area of a circle with radius r is given by A = πr².

Substitute 4 for r.

\sf{A = πr²}

\sf{ \:  \:  \:  \: = π(4)²}

\sf{ \:  \:  \:  \: ≈{\color{magenta}{50.3}}}

<h3><u>Answer</u>:-</h3>

The area of the circle is about 50.3 in².

<h2>======================</h2>

Leto [7]

Answer:

2/8 OR simplified 1/4

Step-by-step explanation:

the denominators have to be the same so you multiply 1/4 by 2 so you get 2/8. Then its 4/8-2/8 so you get 2/8 as your answer

I don't understand this, can somebody please explain it to me?
Artyom0805 [142]
Looking at the equation, you could see that it is in vertex form. Vertex form looks like this: y=a(x-h)^2+k where a is the slope to find the first point away from the origin and (h,k) is the vertex. So, the vertex is (3,-1). The first point away from the origin is up two, over one, so the slope is 2. This means that a is 2. One way you could check this is by putting 2 in for a. If you put it into standard form, it would be 2x^2-12x+17. To find the x in the vertex when the equation is in standard form we use -b/2a. So it would give us 3 for x. If we put in 3 for x, we get -1 for y, so the vertex is (3,-1). This means that a is 2. Sorry for this lengthy answer, hope it helps.
