Cds 3 dvds 5
Sue will use 6 shelves with 3 cds on each and 5 dvds on each.
R^2+2r-33=0 move constant to other side by adding 33 to both sides
r^2+2r=33 halve the linear coefficient, square it and add to both sides, in this case it is just one
r^2+2r+1=34 now the left side is a perfect square...
(r+1)^2=34 take the square root of both sides...
r+1=34^(1/2) subtract 1 from both sides
r=-1+34^(1/2) and -1-34^(1/2)
Option C
The distance of a spin of one full rotation is 31.4 feet
<em><u>Solution:</u></em>
Given that,
A circular merry-go-round has a radius of 5 feet
Radius = 5 feet
We have to find the distance of spin for one full rotation
Distance covered in 1 full of rotation is equal to circumference of circle
<em><u>The circumference of circle is given as:</u></em>

Where "r" is the radius

Thus the distance of a spin of one full rotation is 31.4 feet
So, for the semi circle, we need to find the area of a circle then divide it by 2.
pi times r squared
is the area of a circle with the radius of 4
(I'm going to use 3.14 as pi)
So 3.14 times 16 is 50.24
Divide that by 2 and we get 25.12
For the rectangle at the bottom. We know that the radius is four, so we can cut off 4ft from the height, leaving us with 8.
8 times 8 is 64.
To find the area of the whole figure, we add 64 and 25.12 together, getting 89.12
So the area is 89.12 feet squared.
