What is the radius of a circle whose equation is -10xt6y+18-0? O 2 units
O 4 units
O8 units
O 16 units

Radius, r = 4 units

Step-by-step explanation:

The equation of circle is given by :

We need to find the radius of the circle.

The general equation of a circle is given by :

....(1)

We can rearrange the above equation in terms of the given equation as follows :

On comparing the above equation with equation (1)

h = 5, k = -3 and r = 4

So, the radius of the circle is 4 units.

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

answer;

the correct answer
