Step-by-step explanation:
Given A circular tablecloth with diameter 2 m is to be attached with a lace border. Find the length of lace required. Also find the total cost of the lace at Rs.15 per meter.
- Circumference of a circle is 2πr
- Or we have π x d
- 3.14 x 2 since d = 2 m
- = 6.28 m
- Since circumference of circle is the length of lace required we have
- 2 x 3.14 = 6.28 m
- Therefore the length of the lace is 6.28 m
- Now one meter of lace costs Rs 15
- Therefore 6.28 m of lace costs 6.28 x 15
- = Rs 94.2
- So the total cost of 15 m lace will be Rs 94.2
