the answer is 12 because half of the sphere is 6 unit and the other half is 6 unit then you just add them and you get 12 units
If the problem is
(17 ^ 3) * (79 ^ 7)
The steps are:
Step 1:
(17 ^ 3) = 4913
Step 2:
(79 ^ 7) = 1.92039E + 13
Step 3:
(4913) * (1.92039E + 13) = 9.43488E + 16
If the problem is
(173) * (797)
Step 1:
Multiply both terms with a calculator:
(173) * (797) = 137881
The answer is A (54pi square cm)
I got 0.55 when I did this problem. If I am wrong I am so sorry and please correct me.
