Answer: 4π cm or 12.56 cm
Step-by-step explanation: To find the circumference of this circle, start with the formula for the circumference of a circle which is C = 2πr.
Since the radius is 2 centimeters, we can
plug in 2 centimeters for <em>r</em> in the formula.
So we have (2)(π)(2 cm) which is equal to 4π cm.
So the circumference of this circle is 4π cm.
Remember that π is approximately equal to 22/7 or 3.14 so we can estimate the value of the circumference by plugging in 3.14 for π.
So we have (4)(3.14) which is equal to 12.56.
So the circumference of the circle is
approximately equal to 12.56 cm.

Answer:
I did research and this is what l found from different websites .The inward force of gravity is balanced out by the outward force of pressure to keep the star stable. This stable balance, the outward pressure of hot gases balancing the inward pull of gravity is called the hydrostatic equilibrium.Dont forget to say thanks ✌️
