The statement, "the lateral surface area of cone A is exactly half of that of cylinder B" is: A. True.
<h3>What is the Lateral Surface Area of a Cone and a Cylinder?</h3>
Lateral surface area of cone = πrl
Lateral surface area of cylinder = 2πrh
Lateral surface area of cone A = πrl = πrh
Lateral surface area of cylinder B = 2πrh
This means the lateral surface area of cylinder B is twice that of cone A. Thus, lateral surface area of cone A is exactly half of that of cylinder B.
The answer is: A. True.

Answer:
38.1
Step-by-step explanation:
<span>f(x)=x^3-4x^2+2x+4, we know that f(2)=8-16+4+4=16-16=0
and we can write f(x)= (x-2)Q(x) so Q(x) = f(x) / (x-2)=x²-2x-2
</span><span>x²-2x-2=0 delta = (-1)²- (1).(-2) =1+2=3
</span>x=1-sqrt3 or <span>x=1+sqrt3
finally the zeros are x=2, </span>x=1-sqrt3 or <span>x=1+sqrt3 </span>
