Answer:
Step-by-step explanation:
total increase=350+300=650
C = 2πr
r = radius
c = circumference = 18
Plug in the corresponding numbers with variables.
18 = 2πr
Isolate the r. Divide 2 and π from both sides
(18)/2π = (2πr)/2π
9/π = r
C/π = r is your formula to finding r.

<span>1. We assume, that the number 96 is 100% - because it's the output value of the task. </span>
<span>2. We assume, that x is the value we are looking for. </span>
<span>3. If 96 is 100%, so we can write it down as 96=100%. </span>
<span>4. We know, that x is 33% of the output value, so we can write it down as x=33%. </span>
5. Now we have two simple equations:
1) 96=100%
2) x=33%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
<span>96/x=100%/33%</span>
Salutations!
The temperature changed from 5°C at 6 p.m. to -2°C at midnight. How much did the temperature decrease?
Lets solve this!
To find out how much the temperature is decreased, you need to subtract 5°°C from -2° C. from .
Lets form this into statements ---
Temperature at 6 PM = 5°C
Temperature at midnight = -2°C.
Temperature decreased = 5°C - 2°C = 3° C.
3°C is the temperature decreased.
Hope I helped (:
Have a great day!
