Answer:
7.855
Step-by-step explanation:
A=pi*r^2=3.142*5^2=3.142*25=7.855
Answer: The measure of AC is 32.
Explanation:
It is given that the Points B, D, and F are midpoints of the sides of ΔACE. EC = 38 and DF = 16.
The midpoint theorem states that the if a line segments connecting two midpoints then the line is parallel to the third side and it's length is half of the third side.
Since F and D are midpoints of AE and EC respectively.
So by midpoint theorem length of AC is twice of DF.
Therefore, the length of AC is 32.
Answer:
5
Step-by-step explanation:
Inverse variation equations take the following form:
y = a/x, where a is some constant
We know x=3, y=16 and x=6, y=8 satisfy the equation.
Let's find the value of a.
16=a/3
Multiply both sides by 3
16*3 = a
48 = a
Thus, the equation is:
y = 48/x
You can use the other values of x and y to test, but I'm sure this is the correct equation. :)

Answer:
30
Step-by-step explanation:
Sum of ages= 40
Let the sons age be x
Fathers age = 3 times x or ,3x
So 3x+x=40
4x= 40
x= 40/4
= 10
Therefore the fathers age = 3x
= 3*10
= 30
