Answer:
56.5 inches
Step-by-step explanation:
We are given the area of a circle and we are to find the circumference of the same circle.
We know that the area of a circle is given by so equating the given value to get.
r = 9 inches
Since we now know the radius of the circle so we can find its circumference.
Circumference of circle = =
= 56.5 inches
Answer: 56.54 in
Step-by-step explanation:
The area can be calculated with this formula:
Where r is the radius
And the circumference can be calculated with this formula:
Where r is the radius
Solve for the radius from . Then, tha radius is:
Then, the circumference is:
Answer:
y = 5x + 3
Step-by-step explanation:
Step 1. Find the slope
Each time x increases by 1 unit, y increases by 5 units.
m = slope = 5/1 = 5
Step 2. Find the y-intercept.
y = mx + b
When x = 4, y = 23.
23 = 5Ć4 + b
23 = 20 +b
b = 3
y = 5x + 3
The graph is a straight line with slope m = 5 and a y-intercept at y = 3.
Answer:
y= 5x + 3
Step-by-step explanation:
This is because you solve for slope, which is 5, then plug that into point slope form to get:
y - 8 = 5(x - 1)
y - 8 = 5x - 5
y = 5x + 3.

Answer:
x = 3
Step-by-step explanation:
We should know that:
A straight segment joining the middle of two sides in a triangle is parallel to the third side and equal to half of it.
So,
3x + 1 = (1/2) * 20 = 10
3x = 10 - 1 = 9
x = 9/3 = 3
So, the value of x = 3
