Answer:
12.49 = r
13 = r to the nearest cm.
Step-by-step explanation:
The formula to calculate the volume is:
V = π*r^2*h
We know that V = 10291 cm^3 and Height (h) = 21cm
V = π*r^2*h
10291 = π*r^2*21
Divide both side by 21
10291/21 = (π*r^2*21)/21
490.05 = π*r^2
Now divide both side by π
490.05/π = (π*r^2)/π
155.99 = r^2
Now square root both side
√155.99 = √(r^2) Note: square and square root cancel eachother out.
12.49 = r or,
13 = r

Answer:
A. 40 combinations
we have 8 x 5 = 40
Step-by-step explanation:
Would be 60 as 3 letter words with 5 letters.
The logic is that all letters are being used to their maximum and with numbers 3 within 5 or 5 within 5 the maximum that cna be used is 12 rotation for 3 per letter or 8 rotaion for 5. Then we have 5 rotations = 60 for 3 and 40 for 5. Another logic is the many combinations can you make from the numbers 1 2 3 4 5 not multiplying?
The rearrangement of 5 figure numbers will be 5x4x3x2x1 which is 120 combinations, when you don't repeat a number.
We see that 4+3 +2+1 = 10 and shows less than 5 number combinations at 120, and then we have 5
5:10 ratio = 5/15 = 1/3
This = 1/3 of 120 =40
Then we find answer is 40 as compact 5 letter words from the word tight.
