Answer:
what are the options?
Step-by-step explanation:
Answer: d) 983 11/15 cm3
just multiply all the values because it's volume.
hope this helps :)
(a) and (b) looks correct
(c) Here's how my table looks like:
15 -18 324
27 -6 36
28 -5 25
34 1 1
42 9 81
52 19 361
SUM 828
(d) Take the sum of 828 and divide it by 6 to get 138. Now take the square root of 138 to get the standard deviation:
sqrt(138) ≈ 11.75
Answer:
Step-by-step explanation:
What are we calculating ??? If it is volume of a cone=1/3πr^2h
1/3×3.142×4×4×6
=100.54units cube
To calculate volume of cylinder=πr^2h
V=3.142×4×4×6
V=301.63 units cube
I'm assuming you meant to say a^3. If so, then
a^3 = a*a*a
a^3 = 5*5*5
a^3 = 125
