the radii of rwo circles with centres x and y are 7 cm 4 cm respectively.If the distance between their centres is 11 cm , state whether the two circles will intersect or touch each other
Plzzz these are not free points
Answers
Step-by-step explanation:
they will touch each other
bcz the sum of radii of 2 circls is 11 and itz given the distance b/w the centres is also 11 so of course the circles will touch each other only
hope it helpz
gud day❤️
follo me if you find it helpfull✨
Given : The radii of the two circle with centre X and Y are 7cm and 4cm respectively.
the distance between their centre is 11 cm,
To Find : whether the two circle will intersect or touch each other
Solution:
Join XY using straight line
XY = 11 cm as the distance between their centre is 11 cm,
11 = 7 + 4
= Sum of radius
Hence circles touches each other
if distance between centers is greater than sum of radius then no touching , no intersection
if if distance between centers is less than sum of radius then intersecting circles
