  5. 7 lis 2022 · If you know the diameter, you can find the radius of a sphere by dividing the diameter in half. If you know the circumference, you can find the radius by dividing the circumference by 2 times pi. To learn how to calculate the radius of a sphere using two points on the sphere, keep reading!

  6. 3 sie 2023 · There are four different ways to find the radius of a sphere based on the information given. Let us discuss each of them separately. With Surface Area. The equation to find the radius of a sphere with surface area is derived below. As we know, Surface Area ( SA) = r2, here π = 22/7 = 3.141, r = radius. => r = √ ( SA / (4π)) Thus,

  7. 17 cze 2024 · The volume of a sphere can be found with the following equations: With given radius: V = 4/3 × π × r³, With given diameter: V = 1/6 × π × d³, With given area: V = √(A³ / (36 × π)). Try our equation of a sphere calculator to learn how to calculate the volume of a sphere from its equation.
