Answer:
The area of the shaded region= 37.68
Step-by-step explanation:
Area of the outer circle= 2* 3.14* 36 (Area of the circle=2
r)
=113.04
Area of the inner circle=2*3.14* 12
=75.36
Area of the shaded region= Area of the outer circle- Area of the inner circle
= 113.04- 75.36
=37.68
First, rearrange the equation to standard line format
3x + 9y = 7
9y = -3x + 7
y = -3/9x + 7/9
y = -1/3x + 7/9
now we know the slope of the line (both the existing and the new parallel one, since they both have the same slope)
y = -1/3x + b
plug in the new point in and solve for b
4 = -1/3(6) + b
4 = -2 + b
b = 6
y = -1/3x + 6 is the equation for the parallel line
Answer:
Step-by-step explanation:
Any equation, for example 2r =2/3
That is also 21/4 * 8/5 = (21*8)/(4*5) = 168/20 = 8 and 2/5
