Write the equation of the circle with centre (0, 0) and radius 8.

y^2 + x^2 = 8^2

Step-by-step explanation:

Mathematically the equation of a circle is written as;

(y-a)^2 + (x-b)^2 = r^2

Where (a, b) = (0,0)

r = 8

Substituting these values, we have ;

y^2 + x^2 = 8^2

x^2 + y^2 = 64

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
