Question

Which if the following can't be radius and diameter respectively of the circle

Answer 1

Answer:

make a circle and take your answer

Answer 2

Step-by-step explanation:

Given Which of the following can't be radius and diameter respectively of the circle

1. 4.5 cm, 9 cm

2. 5 mm, 1 cm

3. 3.6 cm, 7.2 cm

4. 4.05 cm, 9 cm

• So we need to find among the options radius and diameter cannot be together.
• Now we have
•                4.5 cm and 9 cm
•               r = 4.5 cm, d = 9 cm
•   Diameter is twice the radius or d = 2r  
•                                                  9 = 2 x 4.5
•                                                  9 = 9  
• So similarly, we have
•                5 mm and 1 cm
•                0.5 cm and 1 cm (1 mm = 0.1 cm)
•      r = 0.5 cm, d = 1 cm
•                  d = 2r
•                   1  = 2 x 0.5
•                    1  = 1  
•          Next we have
•                   3.6 cm and 7.2 cm
•            r = 3.6 cm, d = 7.2 cm
•                      d = 2r
•                     7.2 = 2 x 3.6
•                     7.2 = 7.2
•          So we have
•                     4.05 cm and 9 cm
•                r = 4.05 cm and d = 9 cm
•                        d = 2r
•                         9 = 2 x 4.05
•                          9 = 8.1 which is not equal
• So 4.05 and 9 cm cannot be radius and diameter of a circle
