where C is the circumference, d is the diameter and r is the radius.
The diameter of a circle is a line segment that passes through the center of the circle and has its endpoints on the circle. The radius of the circle is a line segment from the center of the circle to a point on the circle. The diameter of a circle is twice the length of its radius.
If you are given the diameter then use the formula C = πd
If you are given the radius then use the formula C = 2πr

Answer:
I'm guessing it's C because it's the only one that looks right
Answer:
B
Step-by-step explanation:
Because 16 + 2.50 is less than 25 + 0.25x
Answer:
Answer:
Domain = {x /x ≥ -7}
Step-by-step explanation:
The given function y =
Inside the square, negative will not come.
First let's find the domain. x + 7 must be greater than or equal to 0.
x + 7 ≥ 0
Solving x, we get
x ≥ -7
Domain = {x /x ≥ -7}
Hope this will help you.
