We will use formula for circumference of circle:
lets name it as O
O = 2*r * pi
when we express r in this formula we get:
O = 2*2.2*pi
O = 4.4*pi
From this we can see that for given radius, answer is 4.4. The formula only depends on pi and that is what "in terms of pi" means.
Answer:
see below
Step-by-step explanation:
The equation of a circle can be written as
( x-h) ^2 + (y-k) ^2 = r^2
( x-3)^2 + (y+4) ^2 = 36
Rewriting this equation
( x - 3)^2 + ( y - -4)^2 = 6^2
The center is at (3,-4) and the radius is at 6
Susan did not use the formula correctly.
It is x-h and y-k so she needed to rewrite to get the equation in the proper form
Also the radius is r^2 not r/2
Answer:
The equation is in standard form. You will have to convert it to slope intercept form, which is -0.125x + 3.75 = y
Step-by-step explanation:
s = x and a = y, therefore 0.5x + 4y = 15
0.5x + 4y = 15
0.5x + 4y = 15 first subtract 0.5x
4y = -0.5x + 15 then divide all by 4
y = -0.125x + 3.75 slope intercept form
Answer:
x = 8
Step-by-step explanation:
6(x-8)= x- (8)
6x - 48=x - 8
6x- 48 + 48 = x - 8 + 48
6x = x + 40
6x - x = x + 40 - x
5x = 40
5x/5 = 40/5
x = 8
