The cross section at this point forms a circle and its area is pi/32 which equals 9*pi square units.

Not quite.
If the radius of the sphere is R units then the radius of the cross section is sqrt(R2 - 32)
Therefore the cross sectional area is pi*(R2 - 32) square units.

What is the surface area of 5.2 sphere?
Assuming the 5.2 units are the radius of the sphere, then its surface area is: surface_area_sphere = 4πr² = 4 × π × (5.2 units)² = 108.16π units² ≈ 339.8 units²
What is the perimeter of 9.35 and 6.82?
Assuming that the shape is like the cross section of a convex lens, the perimeter is 16.17 units.
What is the volume of a sphere with radius 4?
The formula is (4*pi/3)*r^3, so 256*pi/3 cubic units = 268.08 cubic units. {whatever units r is in}

144pi units2
What is the volume of a sphere with a radius of 12 units?
The volume of a sphere with a radius of 12 units is: 7,238 units3The answer above is correct but the answer ALSO can be 2304 units3
What is the radius of a cross section of a sphere that is 3 units from the center of the sphere?
If the radius of the sphere is R units then the radius of the cross section is sqrt(R2 - 32) Therefore the cross sectional area is pi*(R2 - 32) square units.
What is the area of the cross section of a sphere that is 12 units from the center of the sphere?
That depends on how many units there are in the diameter of the sphere. * * * * * If the radius of the sphere is R units then the radius of the cross section is sqrt(R2 - 122) Therefore the cross sectional area is pi*(R2 - 122) square units.
Units of section modulus?
Section Modulus is moment of inertia divided by distance from center of gravity to farthest point on the cross-section or I/c. The units of Moment of Inertia is distance^4 so the units of section modulus is distance^3 ( distance cubed ). So if your units are in meters: I/c = (m^4)/(m) = m^3
How do you find the diameter of a cylinder if the volume is 1962.5 and the length is 25?
Volume = Length*Area of cross-section So area of cross section = 1962.5/25 = 78.5 units If the cylinder has diameter d then area of cross section = pi*d2/4 So d2 = 4*Area/pi = 99.95 square units. Then d = sqrt(99.95) = 9.997 units of length.
How do you solve the volume of prisms?
It is: cross-section area*length and measured in cubic units
