Example Question #11 : 3 Dimensional Geometry
Find the volume of a sphere with a diameter of 10.
The surface area of a sphere is found using the formula . We are given the diameter of the circle and so we have to use it to find the radius (r).
Plug r into the formula to find the surface area
Example Question #11 : Volume
Determine the volume of the cube with a side length of .
Write the formula for the volume of a cube.
Substitute the length into the formula.
The volume is:
Example Question #11 : Volume
Billy has a ice cream cone that consists of a cone and hemisphere. Suppose the cone has a height of 4 inches, and the radius of the hemisphere is 2 inches. Assuming that the combined shape is not irregular, what is the total volume?
Write the volume for a cone.
Substitute the radius and height. The radius is 2.
Write the volume for a hemisphere. This should be half the volume of the full sphere.
Substitute the radius.
Add the volumes of the cone and hemisphere to determine the total volume.
The answer is:
Example Question #391 : Sat Subject Test In Math Ii
Find the volume of a sphere with a diameter of .
Divide the diameter by two to get the radius. This is also the same as multiplying the diameter by one-half.
Write the formula for the volume of the sphere.
Substitute the radius.
Simplify the terms.
The answer is:
Example Question #13 : 3 Dimensional Geometry
If the side of a cube is , what must be the volume?
Write the formula for the volume of a cube.
Substitute the side length. When we are multiplying common bases with exponents, we are adding the exponents instead.
The answer is:
Example Question #14 : 3 Dimensional Geometry
Determine the volume of a cube if the side length is .
Write the formula for the volume of a cube.
Substitute the side length into the equation.
The answer is:
Example Question #15 : 3 Dimensional Geometry
The radius and the height of a cylinder are equal. If the volume of the cylinder is , what is the diameter of the cylinder?
Recall how to find the volume of a cylinder:
Since we know that the radius and the height are equal, we can rewrite the equation:
Using the given volume, find the length of the radius.
Since the question asks you to find the diameter, multiply the radius by two.
Example Question #11 : Volume
Determine the volume of the cube if the side lengths are .
The volume of a cube is:
Substitute the dimensions.
The answer is:
Example Question #11 : Volume
Determine the volume of a sphere with a diameter of 6.
The radius is half the diameter, which is three.
Write the formula for the volume of a sphere.
Substitute the radius.
The answer is:
Example Question #402 : Sat Subject Test In Math Ii
