Surface = 2 x PI x r x H + 2 x PI x r^2
= 2 x r x h + 2 x r^2
= 2 x 6 x 12 + 2 x 6^2
= 144 + 72
= 216 PI in^2
Answer is A
Answer:
15 early tickets were sold and 5 regular tickets were sold.
Step-by-step explanation:
Let x be the number of early bird tickets sold and y be the number of regular tickets sold.
Total number of tickets sold = 20
Thus, we can write the equation,

Cost of early bird ticket = $10
Cost of regular tickets = $15
Total cost = $225
Thus, we can write the equation,

We solve the equation by elimination method by multiplying first equation by 10 and subtracting.

Thus, 15 early tickets were sold and 5 regular tickets were sold.
36/30=1.2
30/1.2=25
3x+4=25
3x=21
X=7
Therefore a is your answer

Hence, the right option is <u>F</u>.
Answer:
7/4 or 1 3/4
Step-by-step explanation:
Think of 2 2/4 to be 10/4 because you need to multiply the 2 to the 4 which makes 8 and then add 2 to get 10/4.
When you get 10/4 subtract it with 3/4 to get 7/4.
You can leave it as 7/4 or 1 3/4.
