Geometry: Volume Test

The volume of a sphere is given by the formula: $$V = \frac{4}{3}\times \text{π} \times r^3$$ , where r is the radius.

The radius is half of the diameter. If the diameter is d, then the radius r is given by: $$r = \frac{d}{2}$$ .

The volume of a cone is given by the formula: $$V = \frac{1}{3} \times \text{π} \times r^2 \times h$$ , where r is the radius and h is the height.

The volume of a cylinder is calculated using the formula: $$V = \text{π} \times r^2 \times h$$ , where r is the radius and h is the height.

The diameter is twice the radius. If r is the radius, then the diameter d is given by: $$d = 2r$$ .

The volume is $$864\text{π} \text{ cm}^3$$ .

The volume is $$250\text{π} \text{ cm}^3$$ .

To round to the nearest tenth, look at the hundredths place. If it's 5 or more, round up; if it's less than 5, round down.

The volume is simply 175 cm³.

The volume is 2094.4 cm³.
