Answer:
A = 25pi
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
A = pi (5)^2
A = 25pi
If QR is a median, then:

We have NO = 30, MP = 9x - 42 and QR = x + 15. Substitute:

<h3>Answer: A. 6</h3>
Answer:
3, 15 and 30
Step-by-step explanation:
Let the first number be x
Second number is 5 times the first number = 5x
Third number is twice the second number = 2×5x = 10x
The equation becomes;
x + 5x + 10x = 48
16x = 48
x = 48 ÷ 16
x = 3
Therefore the three numbers are x = 3, 5x = 15 and 10x = 30
