Well the area of a sector formula is:
A = (degree/360) × πr²
We know the degree so keep that in mind. The diameter is 15  the radius is half of the diameter so the radius is 7.5. Now we plug these into the equation:
A = (180/360) × π7.5²
A= (1/2) × π56.25
A= 28.125 × π
A = 28.125π

Which fraction is closest to zero? 8/12, 5/8, 6/10, 2/3
konstantin123 [22]
6/10 is the closest to zero because if you simplify all the fractions you can, then convert them into decimals, you can easily find what is closer to zero:

8/12 = 2/3 = 0.66
5/8 = 0.62
6/10 = 3/5 = 0.60
2/3 = 0.66

0.60 or 6/10 is the smaller number ;))

: Karl prepared 12 liters of juice after working 2 hours. How much juice did Karl prepare if he worked for 5 hours? Solve using
Anon25 [30]

Answer:

Karl prepared 30 liters in 5 hours

Step-by-step explanation:

The total amount of juice Karl prepares per unit time can be expressed;

T=U×h

where;

T=total number of liters of juice prepared

U=number of liters prepared per unit time

h=number of working hours

In our case;

T=12 liters

U=U

h=2 hours

replacing;

12=U×2

2 U=12

U=12/2

U=6 liters per hour

The unit rate=6 liters per hour

Solving for 5 hours

Total quantity of juice prepared=Unit rate×number of hours worked

where;

Unit rate=6 liters per hour

Number of hours worked=5 hours

replacing;

Total quantity of juice prepared=(6×5)=30 liters

Karl prepared 30 liters in 5 hours
