Answer:
C. 254.34 in^2
Step-by-step explanation:
The formula for area of a circle is πr² (pi x radius x radius).
Here, only the diameter is shown.
To find the radius, divide the diameter by 2.
18 / 2 = 9
9 is the radius.
We use 3.14 as π (pi).
Now we have the final equation.
pi x radius x radius
3.14 x 9 x 9 = 254.34 in^2.
Therefore, the area of the circle is 254.34 in^2.
Answer:
A) 24
Step-by-step explanation:
Answer:
9 gallons per minute
Step-by-step explanation:
If there are 54 gallons that came out of a pipe within 6 minutes, then we divide 54 by 6 to get how many would come out in 1 minute.
54/6 = 9.
Answer:
x = 4
Step-by-step explanation:
We assume that the given expessions represent the measures of the alternate interior angles, so are equal.
... (4x + 12)° = 7x°
... 12 = 3x . . . . . . . divide by degrees, subtract 4x
... 4 = x . . . . . . . . . divide by 3
_____
Then the angles are 7x° = 28° = (4x+12)°.
I believe it is choice B.
The center is at 2,-6 and the radius is 2.
