Step-by-step explanation:
First of all we need to know the formula for the circumference which is:
We don't have the radius. What we only have is the area; therefore, we must use the area formula and extract the radius from it.
The formula for the area is: Solve for r;
Now that we've found the radius, we simply plug it into the circumference formula.
Answer:
The volume of the cylinder without the prism is approximately 16.690 cubic centimeters.
Step-by-step explanation:
The volume of the cylinder without the prism can be defined as the volume of the entire cylinder (), measured in cubic centimeters, minus the volume of the prism (), measured in cubic centimeters. That is:
(1)
(2)
Where:
- Diameter of the cylinder, measured in centimeters.
- Side of the square prism, measured in centimeters.
- Height of the square prism, measured in centimeters.
If we know that , and , then the volume of the cylinder without the prism is:
The volume of the cylinder without the prism is approximately 16.690 cubic centimeters.
The answer is (A) SSS. The triangles share one side and it is indicated that the other two are congruent.
The scale model for this room would be 27 x 20 inches.
