Circumference of a circle = 2 × π × r
And Diameter = 2 r
Therefore using the formula!
Circumference of the circle with diameter 20 foot :
2 × π × 10 = 20 π foot
Circumference of the circle with diameter 5 foot :
2 × π × 2.5 = 5 π foot
Difference between the sand paintings' diameter = 20 π - 5 π = 15 π foot

Step-by-step explanation:
Please let me know if im correct or not! but i belive i am.
Answer:
12in³
Step-by-step explanation:
V = (B * h) / 3, where B is the area of the base and h is the height.
The base is a rectangle, so it's easy to find it's area:
B = 3 * 2 = 6
Now just find the volume:
V = (6 * 6) / 3 = 36 / 3 = 12in³

Answer:
Midpoint: (-0.5, -1)
Step-by-step explanation:
Solution: M=([tex]x m[/tex],[tex]ym[/tex])/2 or ([tex]x[/tex]+[tex]x[/tex]/2, [tex]y[/tex]+[tex]y[/tex]/2)
add the first [tex]x[/tex] coordinate plus the second [tex]x[/tex] coordinate
do the same for the two [tex]y[/tex] coordinates
then divide them both by 2
should look something like this: (1+0 /2, -7+2 /2)
[tex]x[/tex]= 1+0= 1 / 2 + 0.5 or one half 1/2
[tex]y[/tex]= -7+2= -5 / 2 = -2.5 or four one half -2 1/2
BUT we are not done here, since we cant divide 1/2 no more because it will still give us the same answer (0.5) we move into the next number, -2 1/2, -2 x 1/2 = -1
So our answer is (-0.5, -1)
hoped it helped! <3
The upper-left coordinates on a rectangle are (−4,4), and the upper-right coordinates are (4,4). The rectangle has a perimeter of 20 units.
Draw the rectangle on the coordinate plane.
(If you could please graph this as a coordinate plane and not numbers)
Answers
Answer:
(4,2) and (-4,2)
Step-by-step explanation:
You can see that we have 2 points, which means we have 2 sides of the rectangle. The length of that side is 8. we know that a rectangle has 2 sets of parallel sides, and that they have 2 sets of equal sides. We now know that there are 2 sides with side lengths equaling 16, which we then subtract from 20. We get 4, which we then divide by 2 because there will be 2 more sides. We then move 2 down from both points and take the point which we get from that, which is (4,2) and (-4,2).

An artist enlarged a drawing she made. The original is 3 cm wide and 5 cm tall. The artist set the copier zoom button to 120%. What is the longer dimension of the new drawing?
Pls help
Answers
Answer:
the answer is 6 cm
Step-by-step explanation:
Here’s one way you can solve this problem.
A zoom setting of one hundred twenty percent means that the dimensions of the new copy will be one hundred twenty percent of the dimensions of the original drawing.
First, write the scale that expresses the ratio of the original percent to the copy percent, one hundred to one hundred twenty.
Then, let h represent the height of the copy and write the ratio of copy to original as five centimeters to h centimeters.
Next, write a proportion that equates the two ratios. One hundred to one hundred twenty equals five to h.
Then, cross multiply the terms of the proportion. One hundred twenty times five equals one hundred h.
Next, multiply to get six hundred equals one hundred h.
Finally, divide both sides by one hundred to find h. h equals six.
So, the longer dimension of the new drawing is six centimeters, which is one hundred twenty percent of five centimeters.
