Question

Find the radius of the circle if diameter is 24.8 cm.​

Answer 1

Diameter = 24.8 cm

2 × radius = 24.8 cm

Radius = 12.4 cm

Answer 2

diameter= 24.8

radius= ?

So, for calculating radius we will take,

Radius=d/ 2

r= 24.8/2

r=12.4

CIRCLE:

A Circle is a set of those points in a plane, which are at a given constant distance from a given fixed point in the plane.

Radius:

the constant distance is called the radius of the circle. it is denoted by the letter ‘r’.

Diameter:

diameter of a circle is any straight line segment that passes through the centre of the circle.

for calculating the

diameter of a circle we will use the formula:

d= 2× radius.

And,

for calculating the radius of a circle we will use the formula:

radius= 2/ diameter.
