GCSE Secondary Maths Age 13-17 - Geometry & Measures: Circle Problem - Explained

The video tutorial discusses solving a problem involving circular tables at a conference. It begins by reviewing circle formulas, specifically area and circumference. The problem requires calculating the circumference of a table to determine seating capacity. The teacher calculates the circumference using the diameter and divides it by the space each person needs to find how many people can sit at one table. With 12 tables available, the teacher concludes that only 84 people can be seated, which is insufficient for the 90 attendees. The video ends with a discussion on mark allocation and the importance of remembering circle formulas.

What is the formula for the circumference of a circle?

• pi multiplied by the radius squared

• pi multiplied by the radius

• pi multiplied by the diameter

• 2 multiplied by pi multiplied by the radius

If each person needs 60 cm around the table, how many people can sit around a table with a circumference of 439.82 cm?

• 6 people

• 7 people

• 8 people

• 9 people

How many people can be seated in total if there are 12 tables, each seating 7 people?

• 72 people

• 84 people

• 90 people

• 96 people

What is the total number of people expected at the conference?

• 80 people

• 95 people

• 90 people

• 85 people

What is the final conclusion regarding the seating arrangement for the conference?

• There are enough tables for all attendees.

• There are not enough tables for all attendees.

• The number of tables is exactly sufficient.

• More tables are needed for additional guests.
