Answer:

Step-by-step explanation:

Since the rectangle sits within the larger circle, let's look at it this way:

Area of Shaded Region = Area of Circle - Area of Rectangle

OR

(X) =( pi * r^2 ) - (rectangle length * rectangle width)

Now we fill in the numbers where we know the numbers:

(X) = (pi * (12 cm)^2) - (3cm * 10cm)

(X) = (pi * 144cm^2) - (30 cm^2)

(X) = 144pi - 30

(X) = 452.39 - 30

(X) = 422.39 cm^2

Take the area of the circle and subtract that with the area of the rectangle.

Area of circle= pi*r^2

Area of circle= pi*12^2

Area of circle=144pi

Area of circle= 452.16 cm^2

Area of rectangle: b*h

Area of rectangle: 10*3

Area of rectangle: 30 cm^3

452.16-30=422.16

So the area of the shaded region is 422.16 cm^2

Hope this helped!

svetoff [14.1K]
This can be done easily in a few ways. One, you could do equivelent fractions as this. 16 percent is the same as 16 over 100, or, 16/100, 100 being the total with an = sign with X over 550, or, X/550. you can multiply 16 by 500 and divide by 100 to get $88. Or you could do it my way, (prefered way). take the $550, divide it by 100, then multiply by 16 and get $88. either way you do this, you take away the $88 from $550 and get the sale price of [Drumroll please...]

Calculate the volume<br><br> Please show the steps...
Lerok [7]

Answer:

(a) 2.6 m^2

(b) 3.9 m^3

Step-by-step explanation:

(a)

ABCD is a trapezoid.

A = (B + b)h/2

A = (1.7 m + 2.3 m)(1.3 m)/2 = 2.6 m^2

(b)

The skip is shaped like a prism with trapezoidal bases.

V = area of base * height

V = 2.6 m^2 * 1.5 m = 3.9 m^3

The table and scatter plot below show the number of hits and runs Tyler's baseball team got in each of 12 tournament games.
agasfer [191]

The correct statements are:

  • There is a positive linear equation between the number of hits and the scores
  • The point (7,13) is an outlier.
  • If the trend continues, for a game when Tyler's team gets 20 hits, the number of runs scored would be greater than 10 hits.

<h3>What are the correct statements?</h3>

An outlier is a number that is way smaller or way larger than that of other numbers in a data set. On a trend line, an outlier would be far from the trendline.

A positive linear relationship is when as one of the variables increase, the other variable also increases and the trendline is a straight line that is upward sloping.

wlad13 [49]

Answer:

10

Step-by-step explanation:

df denote degree of freedom

here in question it is given that eleven different video games showing

so here n=11

we know that for calculation of degree of freedom

we can calculate degree of freedom if the sample size n is given degree of freedom is 1 less than sample space

so degree of freedom = sample size -1 =11-1 =10

so the value of degree of freedom that is df is 10
