Answer: 258.31 cm²

<u>Here it's given that ,</u>

  • Circumference of the circle = 57cm.

<u>To Find ,</u>

  • The area of the circle.

We know that ,

→ Circumference = 2πr

Substituting the respective value ,

→ 57cm = 2πr

→ r = 57cm/2π

→ r = 57/(2*3.14) cm

→ r = 9.07 cm

And ,

→ Area = πr²

→ Area = 3.14 * (9.07cm)²

→ Area = 3.14 * 82.26 cm²

→ Area = 258.31 cm²

<u>Hence</u><u> the</u><u> </u><u>area</u><u> of</u><u> the</u><u> circle</u><u> is</u><u> </u><u>2</u><u>5</u><u>8</u><u>.</u><u>3</u><u>1</u><u> </u><u>cm²</u>

I hope this helps.

8x - 3x + 2 - x = ax + b<br> solve for b
kkurt [141]

Answer:

b = -ax + 4x + 2

Step-by-step explanation:

8x - 3x + 2 - x = ax + b

~Combine like terms

4x + 2 = ax + b

~Subtract ax to both sides

4x - ax + 2 = b

~Rewrite

b = -ax + 4x + 2
