Answer:
3
Step-by-step explanation:
If 6 numbers have a mean value of 10, it means that the sum of the numbers divided 6 is equal to 10. This can be expressed as:
x÷6=10
x=60
The new number added will be the 7th number and now the mean is 9. You have to ask what number divided by 7 is equal to 9? This can be expressed as:
y÷7=9
y=63
63-60=3
So the new number added is 3
Answer:
25π square inches.
Step-by-step explanation:
A 3-inch by 4-inch rectangle is rotated about a corner.
So, the maximum area that a point on the rectangle covers will be by the opposite corner point for 360° full rotation.
Now, the length of the diagonal is = inches.
Therefore, the area of the circle will be calculated by 5 inches as the radius will be πr² = π(5)² = 25π square inches. (Answer)
