Answer 1

Correct Question:

Find the radius by given diameter :-

• 20cm
• 28 cm
• 42cm
• 36cm
• 80cm

Answer :-

• 10cm
• 14cm
• 24cm
• 18cm
• 40cm.

Step-by-step explanation:

To Find :-

• The diameter

Given that :-

The diameters :-

• 20cm
• 28 cm
• 42cm
• 36cm
• 80cm

Solution:

We know,

Radius = Diameter ÷ 2,

• 20cm

=> Radius = Diameter ÷ 2

=> Radius = ( 20 ÷ 2 ) cm

=> Radius = 10cm.

• 28cm

=> Radius = Diameter ÷ 2

=> Radius = ( 28 ÷ 2 ) cm

=> Radius = 14cm.

• 42cm

=> Radius = Diameter ÷ 2

=> Radius = ( 42 ÷ 2 ) cm

=> Radius = 24cm.

• 36cm

=> Radius = Diameter ÷ 2

=> Radius = ( 36 ÷ 2 ) cm

=> Radius = 18cm.

• 80cm

=> Radius = Diameter ÷ 2

=> Radius = ( 80 ÷ 2 ) cm

=> Radius = 40cm.

Answer 2

Answer:

The diameter of

20cm is R=>(10cm) ,

28cm is R=>(14cm),

42cm is R=>(21cm),

36cm is R=>(28cm),

80cm is R=>(40cm)

Step-by-step explanation:

=> 20÷2=10

=> 28÷2=14

=> 42÷2=21

=> 36÷2=28

Hope u understand the answer:)
