Answer:
i believe the answer is 142.42 in²
Step-by-step explanation:
what i did was 'separate' the cone and cylinder-
so the volume of cylinder formula is-
v=πr²h
and the volume for a cone is-
v=πr²h/3
now let us fill in the formulas with the information that we have-
v=π*2²*10=125.66
v=π*2²*4=16.76
now let us add the sums together-
125.66+16.76=142.42 in²
good luck :)
i hope this helps

Step-by-step explanation:
Remember that transformation between Cartesian and polar system are:
x=r*cos(α)
y=r*sin(α)
From this we can conclude that:
r=√(x^2 + y^2)
Using trigonometry transformations we can write:
r=sin(2α) = 2sin(α)cos(α)
Now we can multiply both sides with r^2:
r^3 = 2(r*sin(α))*(r*cos(α))
Now using some replacements we can write:
(x^2 + y^2)^(3/2) = 2*x*y
Answer:
12
Step-by-step explanation:
First, find out how wide his shelf is in inches. 2.25*12=27. So his shelf is 27 inches wide. Then divide that by 2.25 to find the number of encyclopedias will fit.
