Suppose the radius of a circle is 8. what is its circumference

Answers

16 because the circumference is 2x the amount of the radius :) please give 5 stars and a thankyou button :)

First, here is the formula for finding circumference using the RADIUS:
C (circumference) = 2 x pi (3.14) x r (radius)
using the DIAMETER:
C = pi (3.14) x d (diameter)
------------
Using the above formula, just plug in the numbers!!
C = 2 x (3.14) x (8)
C = 50.24
50.24 is your answer

if you wanted to use diameter, you should know that diameter is just the radius times 2!

The equation of a line is y = -0.8x + 4. If x = a - 3, what is the value of y when a = -2?A) -4

B) 0

C) 4

D) 8

Answers

Answer:y = 0.8x and y = -0.12x2 + 20

Step-by-step explanation:

X=(-2)-3
X= 6

Y=-0.8(6) +4
Y= -4.8 + 4
Y=.8

Cindy says that 1/3 is an irrational number because the fraction form doesn't terminate. Construct an argument to support or refute Cindy's position.

Answers

It’s not an irrational number because it can be written as a decimal. It is in an infinite decimal but if anything can be written as a fraction it is not a irrational number. :))

Final answer:

Cindy's argument is incorrect. 1/3 is a rational number because it can be expressed as the ratio of two integers. The fact that the decimal representation of 1/3 does not terminate does not make it irrational.

Explanation:

Cindy's argument is incorrect. A fraction is considered irrational if it cannot be expressed as the ratio of two integers. In the case of 1/3, it can be expressed as the division of the integer 1 by the integer 3, so it is a rational number. The fact that the decimal representation of 1/3 (0.333...) does not terminate does not make it irrational. Irrational numbers are decimal numbers that do not repeat or terminate, such as π (pi) and √2 (the square root of 2).

Slope and y intercept

Answers

The equation of a line is given by y = mx + c; where m is the slope and c is the y intercept.
The given equation is 13x - 11y = -12
11y = 13x + 12
y = 13/11 x + 12/11.
Therefore, the slope is 13/11 and the y-intercept is (0, 12/11).
