Answer:
56.25 pi cm^2
Step-by-step explanation:
To find the area of the circle,
we use the formula
A = pi r^2, where r is the radius
We know the diameter is 15 so we can find the radius from
r = d/2 where d is the diameter
r = 15/2
A = pi ( 15/2) ^2
A = pi ( 225/4)
A = 56.25 pi cm^2

Answer: The perimeter is 17.52
Step-by-step explanation:
1. You can plot the points, as you can see in the graph attached.
2. As you can see in the graph, the points are:
And the lenghts <em>AB</em> and <em>EA</em> are:

3. To find the other lenghts, you can apply the formula for calculate the distance between two points:

4. Thefore, you have:

5. The perimeter is:

Answer:
2 meters
Step-by-step explanation:
Given

The question is incomplete as the picture of the tent is not attached.
However, I will use the attached figure to answer the question.
From the attachment, we have:
--- base of the tent
--- length of the tent
Required
Determine the height of the tent
The volume of the tent is:

Where h is the required height.
So, we have:



Make h the subject


<em>The height of the tent is 2m</em>
