The lengths of radii of two circles are 5 cm and 3 cm. The two circles touch externally. Then the distance between the centraes of the circles is

Options

A. 2 cm
B. `2.5` cm
C. `1.5` cm
D. 8 cm

Explanation

Let two circles with centres O and O' touch each other externally at the point C. The radius of the first circle is `5 cm therefore OC= 5cm,` and the radius of the second circle is 3 am, `therefore O'C=3cm.`
Now the distance between the centres of the circeles `=OO'= OC+CO' =5 cm +3 cm =8 cm`
`therefore `(d) is correct
