Answer:
<u>551 square centimeters</u>
Step-by-step explanation:
Finding the radius (r) :
- C = 2πr
- 83.21 = 2 x 3.14 x r
- 83.21 = 6.28r
- r = 83.21/6.28
- r = 13.25 cm
Finding the area :
- A = πr²
- A = 3.14 x (13.25)²
- A = 3.14 x 175.5625
- A = <u>551 square centimeters</u> (nearest whole number)

Answer:
x=5
Step-by-step explanation:
x+5 = -3x+25
Add 3x to each side
x+3x+5 = -3x+3x+25
4x +5 = 25
Subtract 5 from each side
4x+5-5 = 25-5
4x = 20
Divide each side by 4
4x/4 = 20/4
x =5
