Answer:
88 adult tickets and 77 student tickets were sold.
Step-by-step explanation:
Let the number of adult tickets sold be 8x and the number of student tickets sold be 7x.
adult tickets + student tickets = 165 tickets
8x + 7x = 165
15x = 165
x = 165 ÷ 15
= 11
No. of adult tickets sold (8x) = 11 × 8
= 88
No. of student tickets sold (7x) = 11 × 7
= 77
The surface area of the hemisphere with radius r = 19 cm. is 3400.62 square centimeters
<h3>How to determine the surface area?</h3>
The radius is given as:
r = 19
The surface area of a hemisphere is:
Area = 3πr²
So, we have:
Area = 3 * 3.14 * 19²
Evaluate
Area = 3400.62
Hence, the surface area of the hemisphere is 3400.62 square centimeters
