Find the volume of a cylinder if it has a diameter of 8 and a height of 12. Leave your answer in terms of 70.
6471
19270
25670
76870

If we need to choose the closest answer from the above given ones it is 6471.

SOLUTION:
Diameter(d)= 8
Radius(r)= d/2=8/2 =4,,
Height of cylinder (h)= 12

So,
Volume of cylinder = Pi r^2*h
=22/7 * 4^2 * 12
=4224/7
=603.42,,

Answer to your question: a. the fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. the roots are ​ x=1±i7√2 .number of roots=degree of polynomialhere, degree of polynomial is 2 so number of roots will be 2.hope it *_*
