Area of semicircle = 1/2 x pi x radius x radius
radius of semicircle = 14/2 = 7
pi = 3.14 for this question, so

1/2 x 3.14 x 7 x 7 = 76.93
area = 76.93

Answer:

area of a semi circle is 1/2 pi rsquare

since 14 is a diameter

to get the radius divide 14 by 2 =7

1/2* 3.14* 7*7

ans = 76.93

Answer:

See, this is what i do not get. equations like this. People now in days would just by faster internet speed. Why would we need to know this if we will never ever get to use this in our life. Also you could just call the internet cable person. This makes absolutely no since at all. Also who even uses Netflix anymore?

Answer:

The intercepts $(x,y) = (\frac{3}{2},-2)$

Step-by-step explanation:

Given:

$4x-1=3y+5$

Required

Determine the intercepts

The equation is a linear equation and the intercepts of the equation is calculated as thus;

For x intercepts; substitute 0 for y

$4x-1=3y+5$

$4x-1=3(0)+5$

$4x-1=0 + 5$

$4x-1=5$

Add 1 to both sides

$4x-1 + 1=5 + 1$

$4x = 6$

Divide both sides by 4

$\frac{4x}{4} = \frac{6}{4}$

$x = \frac{6}{4}$

Simplify fraction to lowest term

$x = \frac{3}{2}$

For y intercept, substitute 0 for x

$4x-1=3y+5$

$4(0)-1=3y+5$

$0 - 1 = 3y + 5$

$-1 = 3y + 5$

Subtract 5 from both sides

$-5 - 1 = 3y + 5 - 5$

$-6 = 3y$

Divide both sides by 3

$\frac{-6}{3} = \frac{3y}{3}$

$-2 = y$

Reorder

$y = -2$

Hence, the intercepts $(x,y) = (\frac{3}{2},-2)$

The perimeter of the figure is 58 units

The area of the figure is 130 unit square

Your question is not properly formatted and the diagram required to solve the question is missing.

I've included the appropriate diagram.

To calculate the perimeter of the shape, we simply add up the side lengths of the visible parts of the figure.

Having said that, the perimeter is:

$Perimeter = 7 + 8 + 5 + 8 + 3 + 6 + 3 + 5 + 7 + 6$

$Perimeter = 58$

To calculate the area, we use a different approach.

First, we split the figure into 3, we then calculate the area of each sub-figure, and then we add up the calculated areas.

From left to right, we have:

Rectangle 1

$Length = 7\\Width = 6$

Rectangle 2

$Length = 5\\Width = 6+8 = 14$

Rectangle 3

$Length = 3\\Width = 6$

The area of a rectangle is:

$Area = Length * Width$

So, the area of the figure is:

$Area = 7 * 6 + 5 * 14 + 3 * 6$

$Area = 130$

Answer:

Step-by-step explanation:

Terms are the numbers and/or variables within an equation. For example you have 5 terms in that equation:

$3x^2+7y^3+2x+9y-5y^2$

The first term is: $3x^2$

The second term is: $7y^3$

The third term is: $2x$

The fourth term is: $9y$

The fifth term is: $-5y^2$

Coefficients are the numbers in front of variables (this includes negative/subtraction signs). For example you have 5 coefficients in this equation:

The first coefficient is: 3

The second coefficient is: 7

The third coefficient is: 2

The fourth coefficient is: 9

The fifth coefficient is: -5
