Respuesta :

Answer: The answer is: It is given that the circumference (P) of the given circle is 1 cm more than thrice its diameter (D), = 1 + 3D Step 2 We know, the circumference of circle is πD, where D is the diameter. Therefore,⇒ πD = 1 + 3D

Answer:

diameter of the circle is 7.0625 cm and circumference is 22.19 cm

Explanation:

Let the diameter be x.

then the circumference is 3x + 1

Formula for circumference of circle: πd

using the formula:

  • 3x + 1 = π(x)
  • πx - 3x = 1
  • 0.1416x = 1
  • x = 7.0625 cm

Diameter is 7.0625 cm

circumference → 3x + 1 → 3 (7.0625 ) + 1 → 22.19 cm
