Answer:
i believe its the 3rd one
Step-by-step explanation:
Assuming the cylinder is closed at both ends
Surface area = 2 pi r^2 + 2 pi r h = 108
now h = r/2 so we have:-
2pi r^2 + pi r^2= 108
3 pi r^2 = 108
r^2 = 11.459
r = 3.385
so the height h = 1.693 m to nearest thousandth
ii and iii
polynomials are functions of quadratic,cubic,quartic etc involving only a non negative integer power of x.
since option (i) includes negative power(5x^-2) and option iv is a rational function
but option iii can be simplified to a polynomial function (x^2+(4x^3/2-1/2))=x^2+4x^2/2=x^2+4x
Answer:
17.5
Step-by-step explanation:
2.50+0.50=3.00-1.5=2.5
20-2.5=17.5
Use the Pythagorean Theorem.
c^2 = a^2 + b^2. Thus, (2b)^2 = (2√3)^2 + b^2
Simplifying, we get: 4b^2 = 4(3) + b^2, or 3b^2 = 4(3). Then b^2 = 4, and b = +2
