Hello from MrBillDoesMath!
Answer:
Choice E.
Discussion:
Assuming that n >=1, a(n) = 4n -1, then
a(10) = 4(10) - 1 = 39
but that doesn't match any of the answers...... hmm...
BUT
If you meant that a(n) = 4^(n-1), then
a(10) = 4^(10-1) = 4^9 = 262144
which is Choice E.
Thank you,

Answer:
1240.4 mm²
Step-by-step explanation:
The surface area of a pyramid = Area of the all sides + Area of base
Each side is a triangle.
With a regular pentagonal pyramid, the area of each triangle is
For the 5 triangles,
Substituting given values,
Area of base = 440.4 mm²
Surface area of a pyramid = 800 + 440.4 mm² = 1240.4 mm²
