<h3>
Answer:</h3>
A.) 3 pi cm
<h3>
Step-by-step explanation:</h3>
The formula for arc length (s) as a function of radius (r) and central angle (θ) in radians is ...
... s = rθ
Here, you have r=9 cm and θ=(60°/180°)π = π/3 radians, so the arc length is ...
... s = (9 cm)·π/3 = 3π cm
Answer:
3034 I think
Step-by-step explanation:
3034 I think because if u multiply 3700 times 0.82 give you 3034
Answer:
Carrie and Joan have 80 nickels and 40 dimes, respectively, and each one has an amount of money of 4 US dollars.
Step-by-step explanation:
Let be 
and 
the amounts of nickels and dimes that Carrie and Joan have, as 
the total amount of money that both Carrie and Joan have. A nickel is a five cent coin and a dime is a ten cent coin.
The following equations are constructed after a careful reading on statement:
Carrie's amount of money:
(Eq. 1)
Joan's amount of money:
(Eq. 2)
Relation between amounts of coins:
(Eq. 3)
First we eliminate by equalizing (Eq. 1) and (Eq. 2):
Then, we reduce the resulting formula by (Eq. 3):
And rest of variable are now determined:
Carrie and Joan have 80 nickels and 40 dimes, respectively, and each one has an amount of money of 4 US dollars.
Perimeter = 2l + 2w
perimeter = 2(90) + 2(30)
perimeter= 180+60
perimeter= 240 ft
Answer:
1. ratio - 1:4 (side to perimeter)
2. ratio - 4:1 (perimeter to side)
3. ratio - 1: 2 (radius to diameter)
Step-by-step explanation:
for 1. I just put 6/24 which simplies to 1/4. I tried the that with the rest and it equalled to 1/4
for 2. put 24/6 which is 4 (in fraction from 4 is 4/1)
for 3. 4/8 which equals to 1/2
