2 / 10

In a circle, any angle inscribed in a minor arc is -

3 / 10

Equation of a circle is x^{2} + y^{2} − 12x − 16y + 19= 0. Find the radius of the circle.

4 / 10

Find the equation of a circle whose Centre of a circle is on the y-axis at 4 and the radius is 4 units.

^{2}+ y

^{2}- 8y = 0

^{2}- y

^{2}- 8y = 0

^{2}+ y

^{2}-8x - 8y = 0

^{2}+ y

^{2}- 8y = 5

5 / 10

Find the equation of a circle whose radius is 8 units and touches both the x-axis and y-axis.

^{2}+ y

^{2}- 16x - 16y + 9= 0

^{2}+ y

^{2}+ 4xy -16x - 16y + 64 = 0

^{2}+ y

^{2}- 16x - 16y = 0

^{2}+ y

^{2}- 16x - 16y + 64 = 0

8 / 10

Equation of a circle is x^{2}+y^{2}−12x−16y+19=0. Find the center and radius of the circle.

9 / 10

A circle has a diameter of 6 cm. What is the length of the tangent drawn to the circle from a point outside the circle which is at a distance of 4 cm from the center?

10 / 10

Say point (2, 3) is the center of the circle and radius is equal to 5 cm. Then the equation of this circle will be:

^{2}+ y

^{3}− 2x − 4y − 11 = 0

^{3}+ y

^{2}− 2x − 4xy − 11 = 0

^{2}+ y

^{2}− 2xy − 4y − 11 = 0

^{2}+ y

^{2}− 2x − 4y − 11 = 0
