Answer:
Midpoint =1.5,1
radius 4.71699
C = 29.623
A =69.865
Step-by-step explanation:
To find the midpoint, add the endpoint coordinates together and divide by 2
M = (x1+x2)/2, (y1+y2)/2
= (-1+4)/2, (5+-3)/2
= 3/2 , 2/2
=1.5,1
Once we know the midpoint, we can find the radius from one endpoint to the midpoint
d = sqrt( (x2-x1)^2+ (y2-y1)^2)
sqrt( (1.5--1)^2+ (1-5)^2)
sqrt(( 1.5+1)^2 + (4)^2)
sqrt( 2.5^2 +16)
sqrt(6.25 +16)
sqrt(22.25)
4.71699
The circumference is given by
C = 2*pi*r
= 2* (3.14) * 4.717
= 29.623
The area of a circle is given by
A = pi r^2
= 3.14 * 4.717^2
=69.865
$4/8 juice boxes= $0.50 per juice box
Final answer: $0.50 per joice box
Answer:
20
Step-by-step explanation:
Let
= the number of problems Anna completed
<u>Using ratios</u>
5 : 8 =
: 32
![\frac{5}{8} =\frac{x}{32}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B8%7D%20%3D%5Cfrac%7Bx%7D%7B32%7D)
Cross multiply: 5 x 32 =
x 8
160 = 8![x](https://tex.z-dn.net/?f=x)
Divide both sides by 8: 20 = ![x](https://tex.z-dn.net/?f=x)
Therefore, Anna completed 20 problems.
Shouldn’t be 17, that’s the limit
156.25 because a square has 4 sides so it would be 625/4 which equals to the answer 156.25
