Multiply 45 by 2/3 2/3 = 0.66666 so 45*0.6666 = 30
Volume: 2112.5π
Surface Area: 663π
First, let's find the height of the cylinder. Using the formula for lateral surface area, 2*π*r*h:
2*π*13*h = 325π
(divide π by both sides)
26h = 325
h = 12.5 in.
Next, let's solve the surface area of the cylinder using the formula π*r²*h.
π * 13² * 12.5 = π * 169 * 12.5 = 2112.5π.
Next, let's solve the surface area using the formula 2πrh + 2πr².
(2 * π * 13 * 12.5) + (2 * π * 13²) = 325π + 338π = 663π.
We did this same kind of problem in school. All we did was divide the those 2 numbers to figure out the unit price. So, 20/5 = 4 $ per CD.
5 3/4 -4 1/10
= 23/4 -41/10
= 115/20 -82/20
= 33/20
= (20+13)/20
= 20/20+ 13/20
= 1+ 13/20
= 1 13/20
The final answer is 1 13/20~
Suppose U = {1, 2, 3, 4, 5, 6, 7, 8} is the universal set, and P= {1, 3, 5, 7}. what is P'
katen-ka-za [31]
Answer:
P'= {2, 4, 6 ,8}
Step-by-step explanation:
If you mean by P' - ''complement of P'' or ''U\P'' or ''all elements that does not belong to the P '' or ''¬P'' ( which is all the same) then correct answer is
P'= {2, 4, 6 ,8}.
Good luck!!!
