Question

find the circumference from the given information.
1. r = 350cm
2. d = 49m
3. d = 56m

​

Answer 1

Answer:

• If  r = 350cm then circumference = 220 cm
• If  d = 49m then circumference = 154 m
• If   d = 56m then circumference = 176 m

Step-by-step explanation:

1. r = 350cm

The circumference of circle = 2 πr

= 2 × 22/7 × 350

= 2 × 22 × 50

= 220 cm

2. d = 49m

The circumference of circle =   πd

=   22/7 × 49

= 22 × 7

= 154 m

3. d = 56m

The circumference of circle =   πd

=   22/7 × 56

= 22 × 8

= 176 m
