A circle with a radius of 10 inches is divided into sectors by an angle of 45 degrees. What is the length of the arc subtended b
DENIUS [597]

Answer:

The length of the arc is 7.85 in

Step-by-step explanation:

First of all we need to calculate the circumference

To solve this problem we need to use the circumferenc formula of a circle:

c = circumference

r = radius = 10 in

π = 3.14

c = 2π * r

we replace with the known values

c = 2 * 3.14 * 10 in

c = 62.8 in

The length of the circumference is 62.8 in

Now we have to get the relation of the sector with the circle, for this we divide 45° by 360°

45° / 360° = 1/8

we multiply this fraction with the circumference and obtain the length of the arc

62.8 in  * 1/8 = 7.85 in

The length of the arc is 7.85 in

elena-14-01-66 [18.8K]

Answer:

a. The number of people that receive the text in the fourth round are 10³ people

b. The total number of people that receive the text are 1.1111 × 10⁴ people

Step-by-step explanation:

a. The given information are;

The number of people the text is sent to in the first round = 1

In the second round, the number of people the text is sent to by people in the first round = 10

In the third round, the number people the text is sent to by the 10 people in the second round = 10 × 10 = 100 people = 10² people

In the fourth round, the number of people the text is sent to by the people in the third round = 100 × 10 = 1000 people = 10³ people

The number of people that receive the text in the fourth round = 10³ people

b. In the fifth round, the number of people, the people in the fourth round send the text to = 1000 × 10 = 10000 people = 10⁴ people

The total number of people that receive the text = 1 + 10 + 10² + 10³ + 10⁴ people =  11111 people = 1.1111 × 10⁴ people
