Answer:
The number of feet of fencing that he needs will be equal to the perimeter of the circular patio.
We know that the perimeter of a circle of radius R is equal to:
P = 2*pi*R
where pi = 3.14
Then if the radius of the patio is 70ft, the perimeter of the patio will be:
P = 2*3.14*70ft = 439.6 ft
Then he needs 439.6 ft of fencing to enclose the patio.

Hello!
For this you have to find the amount of every color of beads.
300 * 0.30 which is 90 black beads
300 * 0.25 is 75 red beads
300 * 0.15 is 45 white beads
Then you add them.
90+75+45 = 210
Then subtract them from the total
300 - 210 = 90
The answer is 90 blue beads or 30%
Hope this helps!
If you would like to know how much 1 oz costs, you can calculate this using the following steps:
32 oz ... $6
1 oz ... $x = ?
32 * x = 6 * 1
32 * x = 6
x = 6 / 32
x = $0.1875
The correct result would be $0.1875.
