Question

The sum of diameter of two circle is 35 cm
and the difference of their circumference is
66 cm. Find their radii.
$> >$
​

Answer 1

Step-by-step explanation:

Given,

D+D=35

2D=35

D=35/2=17.5

Therefore,17.5 is the diameter of the circle

now, r=17.5/2=8.75(ANS)

: Hence the radius is 8.75.

Answer 2

a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity.
