Area of Circle: $\pi r^{2}$

radius 'r' = 4ft (radius is half of diameter)
$\pi =3.14$

Area equals = 3.14 (4)^2 = 50.24 square feet = 50.2 square feet

Hope that helps!

Answer:

A (-2,8) B (-1,5) C (-6,2)

A(-2,-7) B(-5,-8) C(-8,-3)

Step-by-step explanation:

x,y x,y x,y

A(7,-2) , B(8,-5) , C(3,-8)

translation (7-9),(-2+10) (8-9),(-5+10) ( 3-9),(-8+10)

(x-9) and (y+10) (-2,8) (-1,5) (-6,2)

when rotation 270 degrees counterclockwise around the origin:

A(x,y ) Then A'(-y,x) means switch x and y and make x negative

A(7,-2 ) rotation 270 degrees counterclockwise (-2,-7)

B(8,-5) to (-5,-8)

C(3,-8) to (-8,-3)

What is the volume of a rectangular prism with length 12 in., height 16 in., and width 13 in.? V+lwh. _______in3

Verizon [17]

Hello!

To find the Volume, you'll need to multiply all of the measurements together. So you'll need to multiply 12, 16, and 13 together to get the Volume. First, let's multiply 12 and 16 together to get 192

192*13

Now you're left with 192*13. After you've multiplied them together you should get 2496

You should now have a Volume of 2496in³

I hope this helps!

For the standard normal curve, find the z-score that corresponds to the 30th percentile. -0.47 -0.98 -0.53 -0.12

Nata [24]

We are looking for the Zo score that corresponds to the 30th percentile.
We use the table for the standard normal distribution.
From P (Z <Zo) = 0.3 we search for Zo.
Then we look in the table for the value of Zo that corresponds to 0.3.
Hence, the approximate value is -0.53.
The option is the third

What makes two angles exterior versus interior ?

astraxan [27]

Answer:

Any angle that is on the inside of a shape is called an interior angle.

Step-by-step explanation:

Any angle that is on the outside of a shape is called an exterior angle. An exterior angle is made by extending one of the lines of the shape beyond the intersection point. ... Notice that the two angles make a straight line.

Answer:

Stratified design with color of paper as the blocks

Step-by-step explanation:

The experimental design that this question uses is the stratified design with color of paper as the blocks

A stratified design is one where the population has been divided into strata that are homogeneous. A good number of participants would then be picked for each of the stratum. The homogeneous strata are also known as the blocks and here in this question we have color of paper as the block here.

The students are of different school levels, elementary, high school and middle school. Each of these levels have 100 students. The students in each levels are halved and each half is randomly assigned information on either a white paper or a blue paper.
