The formula to calculate the volume of a cone is:

V = (1/3) * π * r^2 * h

Where:
- V is the volume of the cone
- π is a constant, approximately 3.14159
- r is the radius of the base of the cone
- h is the height of the cone

Plugging in the given values:

V = (1/3) * π * (7 cm)^2 * 25 cm

Calculating:

V = (1/3) * π * 49 cm^2 * 25 cm
V ≈ 1/3 * 3.14159 * 49 cm^2 * 25 cm
V ≈ 1/3 * 3.14159 * 1225 cm^3
V ≈ 3.14159 * 1225 cm^3 / 3
V ≈ 4037.4249 cm^3

Therefore, the volume of the cone is approximately 4037.4249 cm^3.

The formula to calculate the volume of a sphere is:

V = (4/3) * π * r^3

Where:
- V is the volume of the sphere
- π is a constant, approximately 3.14159
- r is the radius of the sphere

Plugging in the given values:

V = (4/3) * π * (7 cm)^3

Calculating:

V = (4/3) * π * 343 cm^3
V ≈ 4/3 * 3.14159 * 343 cm^3
V ≈ 1813.66647 cm^3

Rounding to the nearest 100, the volume of the sphere is approximately 1800 cm^3.

The formula to calculate the volume of a sphere is:

V = (4/3) * π * r^3

where V is the volume of the sphere, π is a constant approximately equal to 3.14159, and r is the radius of the sphere.

Plugging in the given values:

V = (4/3) * π * (7 cm)^3

V ≈ (4/3) * 3.14159 * 343 cm^3

V ≈ 1436.755 cm^3

Therefore, the volume of the sphere with a radius of 7 cm is approximately 1436.755 cm^3.
