Answer 1

Answer:

1. 8 cm

2. 5 cm

3. 12 cm

4. 10 cm

5. 5 cm

6. 4 cm

7. 5.5 cm

8. 2.5 cm

9. 4.5 cm

Answer 2

Answer:

1, diameter = 2 × radius

given radius is 4

2 × 4 is 8

diameter is 8

2, The circle of radius is 2.5cm , the diameter is 5 or circumference is 15.71cm has an area of : 1. 963×10-9 sq . kilometres

3, The radius is 6cm or diameter is 2 cm

so 6 × 2 is 12 the diameter is 12

4, The radius is 5 or the diameter is 2

so 5 × 2 is 10 the diameter is 10

5, If a circle of the radius is 10 then the diameter is 5 cm

6, The length of the radius of a circle must be half of the length so the diameter is 4 cm

7, Diameter is = 2

the radius is 7 so 7 × 2 = 14 cm

8, The diameter is = 2 × radius

= 2 × 5 = 10 cm

9, The Diameter is = 2 × radius

= 2 × 9 = 18 cm

diameter is 18cm
