Answer 1

Step-by-step explanation:

Radius:

1. 6 cm
2. 10 cm
3. 12 cm
4. 15 cm

Diameter:

1. 12 cm
2. 20 cm
3. 24 cm
4. 30 cm

Match this with your question.

Answer 2

Given:

Radius    :  6 cm   10 cm   12 cm     24 cm        

Diameter :  12 cm  20 cm     15 cm   30 cm

(1) Here radius is given 6cm

The diameter of a circle is twice the length of its radius

Diameter =  2 × radius

Diameter =  2 × 6

Diameter = 12 cm

(2) Here diameter is given 20cm

The diameter of a circle is twice the length of its radius

Diameter =  2 × radius

radius = Diameter /2

$Radius = \frac{20}{2}$

radius = 10 cm

(3) Here radius is given 12cm

The diameter of a circle is twice the length of its radius

Diameter =  2 × radius

Diameter =  2 × 12

Diameter = 24cm

(4)  Here diameter is given 30cm

The diameter of a circle is twice the length of its radius

Diameter =  2 × radius

radius = Diameter /2

$Radius = \frac{30}{2}$

Radius = 15 cm

Hence the answers are :

Radius : 6 cm, 10 cm, 12cm, 15 cm

Diameter : 12 cm, 20 cm, 24 cm, 30 cm
