The formula for R radius depends on context. For a circle, R = C / (2π), where C is the circumference. In physics, for orbital radius, it's R = (GM / v^2)^(1/3), where G is the gravitational constant, M is the mass, and v is the orbital velocity.
FAQs & Answers
- What is the formula for radius in a circle? For a circle, the radius formula is R = C / (2π), where C is the circumference.
- How do you calculate orbital radius? The orbital radius can be calculated using R = (GM / v^2)^(1/3), with G being the gravitational constant, M the mass, and v the orbital velocity.
- What is the significance of the gravitational constant? The gravitational constant (G) is crucial in physics as it quantifies the strength of the gravitational force between two bodies.
- How is the circumference related to the radius? The circumference (C) of a circle is directly related to the radius (R) through the formula C = 2πR.
