Answer:
1590.4 square ft
Step-by-step explanation:
r=30 so you need to multiply that by 25% (30*.25=7.5)
30-7.5=22.5
A= pi(r)^2
A=pi*(22.5)^2
A=506.25pi
A=1590.43 or 1590.4 (to the nearest tenth)
If you move the negative on the left side of the second equation over to the right side, then we can see that the equation is equivalent to
.
Remember that an equation
represents a line with slope
and y-intercept
. Since both equations given have a slope of -2, but have different y-intercepts, they are
parallel.

Answer:
Area of the blue border is 100.544 ft²
Step-by-step explanation:
What is the area of the blue border?
Area of a Circle = πr² , where π = 3.142
Where: Outer diameter = 12 ft ==> (half of diameter) Radius (r₁) = 6 ft
Inner diameter = 4 ft ==> (half of diameter) Radius (r₂) = 2 ft
The blue border is the space between the edge of the rug and the inner red circle.
The area of the blue border = Area of outer circle - Area of the inner circle
Area of Outer Circle = πr₁² = 3.142(6)² = 113.112 ft²
Area of Inner Circle = πr₂² = 3.142(2)² = 12.568 ft²
The area of the blue border = 113.112 - 12.568
= 100.544 ft²
