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

Bess [88]

Answer:

The equation to describe the situation is  p-3=17.

And, the total weight of the basket of apples was <u>20 pounds</u>.

Step-by-step explanation:

<u><em>The question is incomplete so, the complete question is below:</em></u>

Liang bought a basket of apples to make pies for her friends. The basket of apples weighed p pounds. Before she had time to make the pies, she ate 3 pounds of apples. There are 17 pounds of apples left to make pies. Write an equation to describe this situation. What was the total weight of the basket of apples?

Now, to write an equation to describe the situation. And to find the total weight of the basket of apples.

So, the basket of apples total weighed = p\ pounds.

Liang ate apples weighed = 3 pounds.

And the apples left for the pies weighed = 17 pounds.

Now, to write an equation describing the situation:

p-3=17.

<u><em>Thus, the equation is </em></u>p-3=17.<u><em /></u>

Now, to get the total weight of the basket of apples:

p-3=17\\\\Adding\ both\ sides\ by\ 3\ we\ get:\\\\p=20

<u><em>Hence, the basket of apples total weighed = 20 pounds.</em></u>

Therefore, the equation to describe the situation is p-3=17.

And, the total weight of the basket of apples was 20 pounds.
