What is the equation of the circle with center (0, 1) and a radius of 10?

victus00 [196]

<u>Answer: </u>

The equation of the circle with center (0, 1) and a radius of 10 is $\bold{x^{2} + y^{2} - 2y-99 = 0}$

<u>Solution: </u>

Equation of circle whose center (h, k) and radius r is given as,

$(x-h)^{2} + (y-k)^{2} = r^{2}$ ---- eqn 1

From question, given that the circle has radius 10 and center (0, 1). We have to find the equation of the circle.

Hence we get, h = 0 ; k = 1; r = 10

By using eqn 1, the equation of circle whose center (0, 1) and radius 10 is given as

$(x-0)^{2} + (y - 1)^{2} = 10^{2}$

On Simplifying we get

$x^{2} + (y-1)^{2} = 10^{2}$

Expand $(y-1)^{2}$ using the formula $(a-b)^{2} = a^{2} - 2ab + b^{2}$

$x^{2} + y^{2} - 2y + 1 = 10^{2}$

$x^{2} + y^{2} - 2y + 1 = 100$

$x^{2} + y^{2} - 2y + 1-100 = 0$

$x^{2} + y^{2}- 2y- 99 = 0$

Hence equation of the circle with center (0, 1) and a radius of 10 is $\bold{x^{2}+y^{2}-2 y-99=0}$

Which of the following sets of sides does not form a right triangle? 6, 8, 10 8, 15, 17 7, 24, 26 5, 12, 13

aev [14]

6^2 = 36
8^2 = 64
36+64=100 = 10^2

8^2=64
15^2=225
64+225=289
17^2 = 289

7^2=49
24^2=576
576+49=625
26^2 = 676

5^2=25
12^2=144
25+144=169
13^2=169

The third set does not make a right angled triangle.
