Answer:
1385 mi to find the area A=21(21)(3.14)
A=441(3.14)
1384.74 round to the nearest 10th is 1385
It should be 1 over 2 or 1 over 11 but im pretty sure its the first one I picked
Answer:
X=20. Our x coordinate is 20.
Step-by-step explanation:
Based from the given slope of 1/2 and a y-intercept of -6, our equation of a line is y=x/2 -6. To remove the fraction we can multiply the equation by 2 to get 2y=x-12. Using this substitute the value of y coordinate 4.
2(4)= x-12
8+12 =x
X=20.
First:
a. ratio of the diameter to the radius
the ratio of the diameter to the radius for any circle is always going to be 2:1 because the diameter is 2 times the legnth of the radius any time so A is not the right answer
b. the degrees of the circle is always 360, the circumference is the distance around the circle, so that would be a good indicator since 360 is constant, but the circumference can change, and if they are the same, then the circles are similar. so B is the right answer
c. Ratio of area to circumference. area=pir^2, and circumference=2pir
this is a good indicator becuase the ratio of the area and the circumference is different for every circle so c is the right answer
D. the ratio of the diameter to the circumference diameter=2r circumference=2pir
circumference=pi time diameter so the ratio of the diameter is 1:pi
this is not a good indicator so this is not the right answer
The answers are B and D, but if the teacher asks for only one, then I would pick c
