Answer:
total surface area of cone is πr (r+l)
22/7 x 3 (3+4)
22/7*3 (7)
22 x 3 ( as 7 that was divided by 22 was cut out with 7 in the bracket)
hence,
TSA of cone = 66pi
Step 1: Write out the function given

Step 2: Interprete the question given

The question requested we find the summation of the first five terms for f(k/2), when k is 1, 2, 3, 4, and 5
Step 3: Find the expression for f(k/2)


Hence, the answer is 33.75
The answer is 21
252 / 12 = 21
I hope this helped :)
C.supplementary is the right one
If you're asking for the measurements, they are...
Length (l) = 4 ft.
Width (w) = 4 ft.
Height (h) = 4 ft.
