First, we find the diameter.
12.56 divided by 3.14 = 4.
Next, find the radius.
4 divided by 2 = 2.
Then, use the formula to calculate the area.
2 times 2 times 3.14 = 12.56 is your area.
In this case, the area and the circumference are the same. Sometimes that is not that case though. Hope it helps! :)
u don't multiple u divide 3 and u do the same for 9 divide it by 3
1000 km/h / 720 km/h = 1.39 hrs
800 km / hr * 1.39 hrs = 1112 km
For this case, since the variation is direct then we have a relation of the form:
Where,
k: proportionality constant
To find k we substitute the following data:
y = 16 when x = 8
We have then:
Clearing the value of k we have:
Then, the equation is:
Substituting the value of x = 16 we have:
Answer:
The value of y for x = 16 is:
Answer:
7 1/2 m
Step-by-step explanation:
C = πd
in this problem, d = 15 which means that r = 15/2 or 7 1/2
