The circumference of a circle is 25.13 cm and the diameter of a circle is 8 cm what is the approximate value of the quotient of c / d

3.142.

Generally, the value of the ratio of the circumference of any circle to its diameter is pi.

Proof?

Circumference, C= π.d

Diameter, d=d

So

C:d=π.d÷d

=d

answer: 590

step-by-step explanation:

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
