Is relationship between 7's in 7,742 and the 7's in 7,785 different in any way

Mathematics

Wittaler [7]3 years ago

It may not look like it, but there is. There are only two 7's in both numbers, but in 7,742, 42 can be divided by 7, and 7,742 can be divided by 7 as well, that gives it 4 relations to the number 7. In the number 7,785, 7 can not be divided into 85 or 7,785. I hope this made sense, I tried to explain it as well as I could

The area of a sector of an circle of a radius 5 cm, formed by an arc of length is 3.5cm. what is the answer
Natali5045456 [20]

Answer:

8.75cm²

Step-by-step explanation:

First we need to find the angle subtended by the arc

L = theta/360 * 2pir

3.5 = theta/360 * 2*3.14(5)

3.5 = theta/360 * 31.4

theta/360 = 3.5/31.4

theta/360 = 0.11146

theta = 0.11146 * 360

theta = 40.13 degrees

Area of the sector = theta/360 * pir^2

Area of the sector = 40.13/360 * 3.14*25

Area of the sector = 40.13/360 * 78.5

Area of the sector  = 8.75cm

Hence the area of the sector is 8.75cm²
