Answer:
The ratio of the circumference to its diameter remains the same.
Step-by-step explanation:
Given,
diameter of circle = 6 inch
diameter is doubled.
New diameter of circle = 2 x 6 = 12 inch
We know that,
The Circumference of a circle is 2 π r or π d where r is the radius of the circle and d is the diameter of the circle.
Circumference of the circle when the diameter is 6 inches.
C₁ = 6π
Ratio of circumference to diameter
Ratio = 
Ratio = π
When the diameter is 12 inches
C₂ = 12 π
Ratio of circumference to diameter
Ratio = 
Ratio = π
Now, the correct statement is the ratio of the circumference to its diameter remains the same if the diameter is doubled.

Answer:
f(3) = -11
Step-by-step explanation:
f(3) means you sub the value that is inside into x
f(3) = -3(3) - 2
= -9 - 2
= -11
X= grade on next test
Add up all scores, divide by 6 and this equals the average of 84
(86 + 91 + 86 + 61 + 87 + x)/6= 84
add in parentheses
(411 + x)/6= 84
multiply both sides by 6
411 + x= 504
subtract 411 from both sides
x= 93
ANSWER: 93 is needed on the next test to have an average of 84
Hope this helps! :)
