Answer:
1/3 and 10/11, or 9/27 and 40/44
Step-by-step explanation:
Simplified 3/9 by 3.
Simplified 20/22 by 2.
Total surface area of cone: πrl + πr²
Assuming the bottom of the cone is closed.
r = r/2, l = 2l
Total surface Area = π*(r/2)*2l + π(r/2)² = πrl + πr²/4
Total Surface Area = πrl + πr²/4
Answer:
2 minutes
Step-by-step explanation:
You can make an equation to model the question.
y=60 initial starting value,
y=(750-720)x, plug in 60 for y,
60=30x, x = 2 minutes
