Answer:
402.123859659
Step-by-step explanation:
first we use A=πr2
this gives us A = 16π
Then multiply by 8 to get 128π
128π = 402.123859659
36
If you set the equation up, it would be n + 5 = 41. If you subtract the 5 from both sides to get n by itself, you get n = 36.
-16t^2+400=0
16t^2=400
take square root on both sides.
4t=20
t=20/4
t=5
Answer
the answer is 8 so your welcome
