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)
It would take 500 minutes for the cost to be $21.50.

Linear equation</h3>
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change (slope) and b is the y intercept.
Let y represent the cell phone bill for x minutes. Using points (230, 17.45) and (370, 19.55):
For 150 minutes:
y = 0.015(150) + 14 = 16.25
For $21.50:
21.50 = 0.015x + 14
x = 500
It would take 500 minutes for the cost to be $21.50.

Answer:
<h2>30% of 10 is 3</h2>
Step-by-step explanation:
We have 30% of x= 3
you want to multiply both sides by 30
which will get you to 3
Answer:
OP = 43.7
Step-by-step explanation:
since the triangle is similar use these ratios.
LM/OP = LK/ON
9/OP = 7/34
do cross multiplication
OP*7 = 34*9
OP = 306/7
OP = 43.71
OP = 43.7
