For instance, if your health plan has an 80/20 co-insurance rate, (coinsurance rates of 70/30 90/10, and flat rates of $5.00 to $20.00 per doctors office visit are also common) your insurance plan pays for 80% of your eligible medical expenses and youre responsible for the remaining 20%. Zip.
The Schwarzschild radius of an object is proportional to the mass. Accordingly, the Sun has a Schwarzschild radius of approximately 3.0 km (1.9 mi), whereas Earth 's is only about 9.0 mm. The observable universe 's mass has a Schwarzschild radius of approximately 13.7 billion light years.
How big around is the Sun? The radius of the Sun is about 700,000 km (435,000 miles). As you know the circumference of a circle is 2 pi r, where r is the radius. That makes 4.4 million kilometers (2.7 million miles) for the circumference. For comparison, the circumference of the Earth is about 40,000 km (25,000 miles), about 100 times smaller than the Sun.
