Answer:
The radius is 5 in
Step-by-step explanation:
The area of a circle is given by the formula
A = pi *r^2
We know the area = 78.5 in^2 (volume would be in^3 area is in^2)
78.5 = 3.14*r^2
Divide each side by 3.14
78.5/3.14 = 3.14/3.14*r^2
25 = r^2
Take the square root of each side
sqrt(25) sqrt(r^2)
5 =r
Answer: 1/21
Step-by-step explanation:
total = 2 + 1 +4 = 7
1/7 x 2/(7-1) = 2/42
2/42 simplifies to 1/21
1/7: 1 doughnut out of a total of 7 items
2/(7-1): 2 mint cookies are available in the pool out of 6 items -> since one item has already been chosen without replacement, so now the total is 6.
Step-by-step explanation:
a.) 6x - 12
= 6( x - 2)
b.) 4ay - 24az
= 4a( y- 6z)
The Answer is: $4.50 for 75 copies. Each copy is .06
