Hey there! I'm happy to help!
First, let's find the radius. The radius is half of the diameter.
8.4/2=4.2
Here's how to find the area of a circle.
Square the radius.
4.2²=17.64
And multiply by pi (3.14 in our case)
17.64(3.14)=55.3896
We round to the nearest tenth, giving us an area of 55.4 ft²
Have a wonderful day! :D
purchasing a flying car is 0, The sun rising in the morning is 1,
the result of coin toss being tails is 1/2,pulling a marble from bag of red marbles is 1.
Step-by-step explanation:
- Probability occurrence of an event at any point of time.
- Probability always lie between 0 -1.
- Purchasing a flying car is 0 because it is not commercialized.
- The sun rising in the morning is 1 because it will always rise in morning.
- Tossing a biased or a fair coin has two sides which is either head or tail.
- Since it shares two options it is 50/50 or 0.5/0.50.
- Since there is only red marble in a bag probability of picking a red is 1.
Answer:
The required equation is
Charges = $(22 * No of Rooms cleaned)
Step-by-step explanation:
Direct Relation:
The relation ship in which if one quantity increase then it results in the increase of the other quantity too and if it decreases then other quantity will decrease too.
it is represented by
a∝b
a= kb
where k is constant of proportionality
Now for the given question
Charges is directly proportional to no of rooms cleaned
It is
Charges ∝ No of rooms cleaned
It could be written as
Charges = K * No of rooms cleaned
Here k is given as $22 for each room
so
it becomes
Charges = $(22 * No of Rooms cleaned)
which is the relationship in form of equation!!!
