Number of general admission tickets sold is 75
<u>Step-by-step explanation:</u>
Step 1:
Let the number of general admission tickets be x, then the number of student ID tickets = 200 - x. Total cost of tickets sold = $625
Cost of general admission tickets = 5x
Cost of student ID tickets = 2(200 - x) = 400 - 2x
Total cost of tickets = 5x + 400 - 2x = 625
⇒ 3x + 400 = 625
⇒ 3x = 225
⇒ x = 75
Answer:
Method 1 (using the area of a whole circle and dividing by 4)
First work out the area of the whole circle by substituting the radius of 8cm into the formula for the area of the circle:
A = π ×r²
= π ×8²
= 64π (leave the answer as an exact solution as this need to be divided by 4).
So all you need to do now is divide the answer by 4:
Area of a quadrant = 64π ÷4 = 16π = 50.3 cm² to 3 significant figures.
Method 2 (using ¼ πr²)
Substitute r = 8 directly into the formula A = ¼ πr².
A = ¼ πr².
A = ¼ × π × 8².
A = 50.3 cm²
As you can see it gives exactly the same answer as method 1.
