Answer:
D
Step-by-step explanation:
A = (pi)(r)^2
A = (3.14)(3.7)^2
A= ~43
You divide circumference by 3.14 to find the diameter
Divide the diameter by 2 to get the radius
Use the formula for area with the radius that you just found and you should get your answer
Answer:
X= 23 degrees
Step-by-step explanation:
117 degrees minus 94 equals x
x=23
Let us consider the ration of two numbers be x
The two numbers are 5x and 3x
Since two numbers differ by 18, we can write the equation
5x – 3x = 18
2x = 18
x= 9
Therefore the two numbers are
5x = 5 x 9 = 45
and
3x = 3 x 9 = 27
∴ The two numbers are 45 and 27.
