What is the surface area of a sphere with a radius of 13 units?
allochka39001 [22]

Answer:

2,122.64 square units or 676 \pi units squared

Step-by-step explanation:

The surface area of a sphere can be found using the formula A=4\pi r^2. Since the radius is 13 units, substitute r=13.

SA=4\pi r^2\\SA = 4 \pi (13)^2\\SA = 4 \pi *169\\SA = 2122.64

Without multiplying 3.14 for \pi, the answer is

SA = 169*4 \ pi\\SA = 676 \pi

Another sigma notation question. Please check. Hopefully I did this one correctly!
Neko [114]

Answer:

Your answer is correct.  The series is a geometric series with common ratio -1/4 and first term 40.  So each term is:

an = 40 (-1/4)^(n−1)

So the sum of the first 10 terms is:

∑(n=1 to 10) [ 40 (-1/4)^(n−1) ]
