Answer:
{sqrt(2) 2 sqrt(a), 8 b + 3, 3 - 27 c, 18 sqrt(2) a b c + 3}
Step-by-step explanation:
Using the formula for area of a circle:
Area = pi x radius^2
Replace area with the given value:
39.62 = pi x radius^2
Divide both sides by pi
Radius^2 = 39.62/pi
Radius^2 = 12.62
Solve for radius by taking the square root of both sides
Radius = sqrt(12.62)
Radius = 3.55 cm
Answer:
Dont count me if I'm wrong but if you divide 225 by 30 you get 7.5
So your answer should be 7.5
Answer:
r = 8 units
Step-by-step explanation:
The circumference is calculated using 
. Substitute C = 50.24 units. Solve for the radius.
