Answer:
The surface area is 
Step-by-step explanation:
<u>Step 1: Determine the area of the bottom</u>



<u>Step 2: Determine the area of the triangles</u>




There are two of these right triangles on every side which means that we have 8 of these triangles so we multiply the area that we got by 8.


<u>Step 3: Combine the area to get the surface area</u>


Answer: The surface area is 
This is nonfiction and that would c I.09357 0.6543
The formula for area of a circle is r² x π.
Since we know the diameter, we can firstly divide by 2 to find our radius.
4/2 = 2
Now that we know the radius, we can substitute it in and square the value.
(2)² x π
(4) x π
Since we're finding the area in terms of pi, we won't multiply by pi, giving us the answer of 4π.
Therefore, the area of the circle is equal to 4π.
