consider a circle with a radius of 10 centimeters. What is the length of the arc that measures 60° for the given circle.
Kobotan [32]

Answer:

3 1/3π

Step-by-step explanation:

First, you have to find the circumference. The circumference, based on the equation of 2rπ, comes out as 20π. Since you have to find the length of the arc that is 60 degrees, divide 60 by 360 to see how much of the circle 60 degrees is. It results in 1/6, so then you simply have to multiply 20π by 1/6.

Plz help its so confusing
aleksklad [387]

Answer:

20, 4

Step-by-step explanation:

Let's assume total number of students registered is n

Last week n/4 people are absent

so people present are n - n/4 = <u>3n/4</u>

Today after return of Jen  1/5 n are absent

so people present are n - n/5 = 4n/5

which is also equal to last week present people + 1 (Jen)

= 3n/4 + 1

= (3n + 4) / 4

so (3n + 4) / 4 = 4n/5

=> 3n + 4 = 4n/5 * 4

=> (3n + 4) * 5 = 16n

=> 15n + 20 = 16n

=> 20 = n

=> n = 20

So total students registered for class is 20

today no of people absent = n/5 = 20/5 = 4

Gelneren [198K]
All you have to do is addition. 2+5+4=11. Or you can break it down and go 2+5=7 and then 7+4=11. Or 5+4=9 then 9+2=11. Or 4+2=6 then 6+5=11.

A can of pineapple has a height of 13 cm and a diameter of 10 cm, What is the surface of the label that is on it in cm^2
labwork [276]

Answer:

408.46cm^2

Step-by-step explanation:

Given data

Height= 13cm

Diameter= 10cm

Radius= D/2= 10/2= 5cm

The area of the curved surface will be = 2πr × h = 2πrh

substitute

Area of the curved surface = 2πrh= 2*3.142*5*13

Area of the curved surface = 2πrh= 408.46cm^2

Hence the area of the curve surface is 408.46cm^2
