Question

from a point P, the lenght of the tangent to a circle is15m and distance of P from the centre of the circle is 17m. Than what is the radius of the circle​

Answer 1

Answer:

17^2 = 15^2 + r^2

17^2 = 15^2 + r^2289 - 225 = r^2

17^2 = 15^2 + r^2289 - 225 = r^264 = r^2

17^2 = 15^2 + r^2289 - 225 = r^264 = r^2r = 8 m
