Answer: Choice D. 2, 6, 12, 20</h3>
=============================================
Work Shown:
Plug in n = 1
c(n) = n(n+1)
c(1) = 1(1+1)
c(1) = 1(2)
c(1) = 2
The first term is 2
-------------
Plug in n = 2
c(n) = n(n+1)
c(2) = 2(2+1)
c(2) = 2(3)
c(2) = 6
The second term is 6
-------------
Plug in n = 3
c(n) = n(n+1)
c(3) = 3(3+1)
c(3) = 3(4)
c(3) = 12
The third term is 12
-------------
Plug in n = 4
c(n) = n(n+1)
c(4) = 4(4+1)
c(4) = 4(5)
c(4) = 20
The fourth term is 20
-------------
The first four terms are: 2, 6, 12, 20
5×70=5×7=?tens=? sorry i didnt know all of them
So to find the perimeter of a square, we must add all of the sides together.
We know that a square's sides are all equal in length and that a square has 4 sides. So that means we need to add 4.7 four times to get the perimeter.
4.7 + 4.7 + 4.7 + 4.7 = 18.8
So the perimeter of the square is 18.8 cm.
Hope I helped!
The beach ball can hold 37.15 cubic feet of air
<u>Solution:</u>
Given that the beach ball has a diameter of 4.14 feet
We are asked to find how much air can fill the ball. This means that we have to find the volume of the ball
<em><u>Finding volume of ball:</u></em>
Given diameter = 4.14 feet
We know that radius is half of diameter
Since ball is a sphere, Volume of sphere is given as:
By substituting the value of radius we get,
Hence the beach ball can hold 37.15 cubic feet of air
