Answer:
(C) 30πcm
Step-by-step explanation:
In order to find circumference you use the formula C (circumference)=2(pi)(r) in which r is the radius. In this case, two and 15 are thirty so to find the circumference all you have is the equation 30 times pi centimeters is equal to the Circumference.
The Carbon Dioxide in the atmosphere is only very small
relative to other gases. Typically, it only consists about 0.038 percent or
0.04 percent of the gases in the atmosphere.

Even though it is only small, CO2 is very important since it is one of the
greenhouse gases which ensures that the Earth stays warm.</span>
For all of them you can just simplify to their lowest fractions like this and they'll still be equivalent 2/10, 1/4, 9/10
Answer:
Radius: 8
Circumference: 50.27
πr^2 = Area of circle
201.06 = πr^2
divide by pi
201.06 / π = 63.9993857161 = 64
64 = r^2
Square root both sides to get radius.
= 8
r = 8
Circumference = π x diameter
Diameter = 2 x radius
Circumference = π x 16 = 50.2654824574 = 50.27
Answer:
To get this answer you’d just divide 5% by 100, and you’d get 0.05. I hope this helps!
