What is the question here?
Answer:
The total amount of screen needed is 22 ft^2
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
The surface area of a rectangular prism is equal to
where
B is the area of the base
P is the perimeter of the base
h is the height of the rectangular prism
<em>Find the area of the base B</em>
<em>Find the perimeter of the base P</em>
The height of the prism h is
substitute the values
The total amount of screen needed is 22 ft^2
Step-by-step explanation:
555-22 = 533
Answer: The volume of the apartment is 2,160 ft3.
An hourly rating of 2.5 BTUs per cubic foot is required, so multiply the total volume by 2.5.
Arthur needs an air conditioner that will provide 5,400 BTUs to properly cool his apartment
Step-by-step explanation:
- Correct. This is the distance around the circle, aka the perimeter.
- False. Going from center (O) to the point A is the radius, which is half the diameter. Answer: radius
- Correct. The diameter is a chord that goes through the center. A chord is any segment where the endpoints are on the circle's edge.
- Correct. There are three radii shown in this diagram. The other radius is OC. Segment BC is a chord that is neither a diameter nor a radius.
In short, all you need to do is change "diameter" to "radius" in question 2. Other than that, you're perfect.
