Kelsey bought a circular rug that is 12 feet in diameter. The rug has a blue border and a red circular center that is 4 feet in diameter. What is the area of the blue border? (round to the nearest tenth place aka after the decimal)

Note: Explain Step-by-step

The blue area is the difference between the area of the 8 ft diameter rug and the area of the 6 ft diameter rug.

Step-by-step explanation:

From each diameter, you can figure out the appropriate radius. Then find the area of the larger circle & subtract from that the area of the smaller circle, using the formula Area = pi•radius2 for each circle.

Please mark me as brainliest, hope this helped.

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

step-by-step explanation:

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
