Question

find the diameter of a circle whose radius is 2.5​

Answer 1

Answer:

diameter d = double the radius here the answer is 5.0

Answer 2

$\mathtt{\huge{\underline{\bf{\red{Answer :-}}}}}$

$\setlength{\unitlength}{1 cm}\begin{picture}(0,0)\put(2,2){\circle{19}}\put(1.3,2){\line(2,0){1.4}}\put(2.1,2.1){\scriptsize{5cm}}\put(2,2){\circle*{0.1}}\end{picture}$

The radius is 2.5 cm.

The diameter of a circle = 2r

➝ 2 × 2.5

➝ 5 cm

Knowledge :-

A circle is a combination of points 360° around the centre point in curved form.

• Area of a circle is πr².

• Circumference of a circle is 2πr .

• Diameter of a circle is 2 r.

The radius is the distance between centre to any on point on circle .

The diametere is the largest distance between any two point of the circle passing through the centre.

The parts of a circle are arcs ,curves & , point.

All the point from centre making radius are equidistance in a circle.

Other than the diametere the distance between any two point of the circle is its chord.

The diametere is the largest chord of the circle.
