Answer:
D
Step-by-step explanation:
The area and the radius of a sphere are related by the formula:
A=4πr^2
Let’s say this is A1 and r1
Now the radius is tripled. This means r2 = 3r1
The new area thus becomes: A = 4 * (3r)^2 * π = 36πr^2
Comparing A1 and A2 , we can see that A2 = 9A1
Answer:so the answer would be 11 dollars$ if she bought 9 tickets and a 5 dollar serice charge they would be 11$. put 11x9=99+5=104
Step-by-step explanation:
smallest triangle 5.7/11,
medium triangle 11/x
5.7/11=11/x
x=11*11/5.7≈21.2 (longer leg of the medium triangle)
difference between 6 and 5.7 is 6-5.7=0.3 ,
screen going to be 0.3 feet less, than leg of the medium triangle that was found
21.2-0.3=20.9 ft
