Find the area of the triangles, multiply that value by 4. Then add that sum to the surface area of the base. The total surface area is equal to 28.
2n + 8 ≤ 25 |subtract 8 from both sides
2n ≤ 17 |divide both sides by 2
<u>n ≤ 8.5</u>
The answer to your question is 64.
I think it is d cause I no
The answer is g. 47.1
you use the formula
c= π d
then plug is 15 for d and you should get the answer
