The radius of a circle: r = ?
C = 22 m
C = 2 r π
r = C /( 2 π )
r = 22 / ( 2 · 3.14 )
r = 22 / 6.28
Answer:
r = 3.5 m
Answer:
8 hours.
Step-by-step explanation:
The initial water level is 24.8 meters, and the rate of water level drop is 2 meters/ hour, that means after 
hours the water level 
will be
Now we want water level to be 8.8 meters, I.e 
, therefore, we have:
we solve the equation for :
it will take 8 hours for the water level to drop to 8.8 meters.
Answer:
A. (3 × 4) + (3 × 7)
3(4 + 7)
B. (5 × 9) - (5 × 6)
5(9 - 6)
C. 32 +16 = 48
8 (4 + 2)
D. 4(100 - 3)
97 × 4
E. 7(60 + 6)
66 × 7
Step-by-step explanation:
An example of a domain that can be illustrated from the information given will be D(x) = 32.
<h3>Domain and range</h3>
An example based on the information given is "A gas tank in John's car can hold 20 gallons of gas and the car gets 32 miles for every gallon".
John fills up the tank and then goes on a trip. In this case, the distance that will be travelled on one tank will be:
D(x) = 32x
In the above function, it should be noted that the number of gallons can be from 0 to 20. Since he gets 32 miles per gallon, the car can travel 640 miles.
In this case, the domain is the number of gallons that can be used. The number of miles will be the range.
