The circumference of a circle is 25.12 meter. What is the diameter of this circle? Use 3.14 for pi

Formula C= 2(3.14)(R)

We are looking for R first, so
=
——
2

r= 25.12
————
2(3.14)

r= 25.12
———-
6.28

r= 4

diameter= r(2)
4(2)= 8

THE DIAMETER OF THE CIRCLE IS 8

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 *_*
