3 dni temu · Observe that the volume of the sphere can be rewritten as 36\pi=\frac {4} {3}\pi \times 3^3. 36π = 34π ×33. Then, since the volume of a sphere with radius r r is \frac {4} {3} \pi r^3 , 34πr3, it follows that the radius of the sphere in this problem is r=3. r = 3.

2 dni temu · The formula to calculate the density of a sphere involves the volume of a sphere and its mass: \[ D = \frac{m}{\frac{4}{3}\pi r^3} \] where: \(D\) is the density in kilograms per cubic meter (kg/m³), \(m\) is the mass of the sphere in kilograms, \(r\) is the radius of the sphere in meters. Example Calculation

2 dni temu · The formula for the volume (V) of a sphere is given by: V = 4/3 * π * r³ Answer The formula for the surface area (A) of a sphere is given by: A = 4 * π * r² where r is the radius of the sphere. However, you have not provided the radius of the sphere. Please provide the radius so that we can calculate the volume and surface area.
5 dni temu · Formula used: Surface area of a sphere is $4\pi {r^2}$ where ‘r’ is the radius of the sphere and $\['\pi '\]$ is equal to 22/7 or 3.14. Complete step-by-step solution: (i)10.5cm In this case, we are given that the radius of the sphere is 10.5cm. r=10.5cm. Surface area of the sphere $ = 4\pi {r^2}$ $ = 4 \times \pi \times r \times r \\
