Nicole is a wedding planner. The guests are to sit at a circular table with a diameter of 180cm. Each guest needs 70cm around the circumference of the table. There are 18 tables at the venue. A total of 145 guests are attending the wedding. Are there enough tables?

Answer 1

 

Hi Maddie

Circumference of each table = 2* pi* R

= 2*3.14 * 90 = 565.2 cm

each person needs 70 cm

so number of persons on on table =565.2 /70 = 8 max

 

Total No. of table = 18

Max No. of persons adjusted  = 18 * 8 = 144
