The area of circle is 113.04 in^2

Further explanation:

The area of circle is calculated by using pi and radius.

We are given

Diameter = d = 12 inches

pi = π = 3.14

r = \frac{d}{2} = \frac{12}{2} = 6\ inches

Area = \pi r^2\\= 3.14 * (6)^2\\= 3.14 * 36\\=113.04\ in^2

The area of circle is 113.04 in^2

Keywords: Circle, Area of Circle

Please Help! In dire need~!
timama [110]

Answer: The solution is 3\frac{1}{3}

Step-by-step explanation:

since we have given that

\frac{2}{3}\div \frac{1}{5}

we need to solve it using area models:

As we know that "In fractions, division is changed into multiplication by reciprocating the next term to make it possible to solve":

So, It turns into model of area "Area of rectangle "

Area=Length\times Breadth\\\\Area=\frac{2}{3}\times \frac{5}{1}\\\\Area=\frac{10}{3}=3\frac{1}{3}

Now, verifying by using numerical operations only.

\frac{\frac{2}{3}}{\frac{1}{5}}\\\\=\frac{2\times 5}{3\times 1}\\\\=\frac{10}{3}\\\\=3\frac{1}{3}

Hence, verified.

1. Solve -y/12 = 6<br> 2. Solve x/4 = 8
OlgaM077 [116]

1. Isolate the y. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.

First, multiply 12 to both sides

-y/12(12) = 6(12)

-y = 6(12)

-y = 72

Isolate the y. Divide -1 from both sides

-y/-1 = 72/-1

y = -72

-72 is your answer for y

--------------------------------------------------------------------------------------------------------------

2. Isolate the x. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.

x/4 = 8

First, multiply 4 to both sides

x/4(4) = 8(4)

x = 8(4)

x = 32

32 is your answer for x

--------------------------------------------------------------------------------------------------------------

hope this helps
