**Answer:**

What is 1 million times 4358

**Step-by-step explanation:**

You add 6 zeros on the end since million has 6 zeroes.

This is a combination in which you choose 4 from 10.

The formula is

combinations = 10! / 4! * (10-4)!

combinations = 10! / 4! * 6!

combinations = 10 * 9 * 8 * 7 * 6! / 4! * 6!

combinations = 10 * 9 * 8 * 7 / 4 * 3 * 2

combinations = 10 * 3 * 7

combinations = 210

Answer: each guest gets 4.19 cm²

Step-by-step explanation:

The cake is a circle. The area which he cuts for himself is a sector with a central angle of 120 degrees. The formula for determining the area of a sector is expressed as

Area of sector = θ/360 × πr²

Where

θ represents the central angle

π is a constant whose value is 3.14

r represents the radius of the circle.

From the diagram,

r = 4cm

Therefore, area of the cake that he cut for himself is

120/360 × 3.14 × 4²

= 16.75 cm²

The total area of the cake is

3.14 × 4² = 50.24 cm²

Therefore, the rest of the cake is

50.24 - 16.75 = 33.49 cm²

The amount that each guest gets would be

33.49/8 = 4.19 cm²
