Question

If the length of lace required for a circular table cloth is 314 cm, then diameter of the table is...

Answer 1

Step-by-step explanation:

length of lace = circumference of circle( in our case circular table )

so we know that

circumference of circle = 2πr where r is radius and π is constant with value equal to 22/7

314= 2πr

314= 2×(22/7)×r

(314×7)/(2×22)= r

r= (7×157)/22

r= 49.9 cm approx 50 cm
