Diameter – LM

Radius – OP

Chord – CD

Practice set 29

1. If the radius of a circle is 5 cm, what will its diameter be?
Ans:
Radius = 5 cm

 

Diameter = 2 × Radius
∴ Diameter = 2 × 5
∴ Diameter = 10 cm

 

Diameter will be 10 cm.

2. If the diameter of a circle is 6 cm, what will its radius be?
Ans:
Diameter = 6 cm

 

Radius = Diameter ÷ 2
∴ Radius = 6 ÷ 2
∴ Radius = 3 cm

 

Radius will be 3 cm.

3. Complete the following table by filling in the blanks.

Ans: 

(1) Radius = 4 cm

 

Diameter = 2 × Radius 

∴ Diameter = 2 × 4 

∴ Diameter = 8 cm

 

Diameter will be 8 cm.

 

(2) Diameter = 16 cm

 

Radius = Diameter ÷ 2 

∴ Radius = 16 ÷ 2 

∴ Radius = 8 cm

 

Radius will be 8 cm.

 

(3) Radius = 9 cm

 

Diameter = 2 × Radius 

∴ Diameter = 2 × 9 

∴ Diameter = 18 cm

 

Diameter will be 18 cm.

 

(4) Diameter = 22 cm

 

Radius = Diameter ÷ 2 

∴ Radius = 22 ÷ 2 

∴ Radius = 11 cm

 

Radius will be 3 cm.
