Answer:
8 pi yd.
Step-by-step explanation:
The circumference of a circle can be calculated as follows:
c =
Where r is the radius of the circumference.
So in our case:
c = yd.

4/10 in simplest form:
First, we need to find the greatest common factor (GCF) of the numerator (4) and denominator (10). To do this, we'll list the factors of each number, find the common factors, and then the greatest.
Factors of 4: 1, 2, 4
Factors of 10: 1, 2, 5, 10
The common factors are 1 and 2, so the greatest common factor is 2.
Second, our next step is to divide the numerator and denominator by the GCF we recently found which is 2.
Third, our last step is to rewrite our fraction in its simplest form. Above, we collected our brand new numerator and denominator.

Answer in decimal form:
Hi here are the answers:)
Part A:
x = 3
Part B:
A = (3, 2)
Part C:
You can find the vertex by finding the mid-point of the focus and directrix. So the vertex is (-1, 2)
Part D:
The parabola opens left. This is because the parabola always opens toward the focus.
Part E:
The value of p is the distance from the focus to the vertex or the vertex to the directrix. To find p you can minus x-coordinate of focus with x-coordinate of the directrix, then divide it by 2. So this will be: -5-2/2 = -4
Part F:
p = -4
Part G:
Part H: image is attached down below. Fyi the C should be V (vertex)
Part I:
*I'm not really sure about this one*
Part J:
1. x = 1/4 (y-3)>2+3
2. x = 1/12 (y +1)>2 +5
*I'm not really sure about this one either srry:(*
Hope this helped bai bye.
