Answer:
Surface Area = 282.6 cm²
Step-by-step explanation:
Formula: SA = 2
rh + 2r²
SA = 2rh + 2r²
SA = 2(3.14)(5)(4) + 2(3.14)(5)
SA = 2(3.14)(5)(4) + 2(3.14)(25)
SA = 125.6 + 157
SA = 282.6 cm²
We are basically given most of what we need to calculate the height of the cannonball.
We use the formula h = –16t+ vt + s to find the height requested.
Let v = 160
Let s = 10
Let t = time in seconds
Was the value of t included? We need to know t to plug into our formula.
You know everything else except for t. Go back to your notes to search for t. Afterward, plug the value of t and everything else given above into the formula and calculate to find h.
6 · e^(4x - 2) = 3
e^(4x - 2) = .5
ln e^(4x - 2) = ln (.5)
4x - 2 = ln (.5)
4x = ln (.5) + 2
x = (ln (.5) + 2)/4
x = 0.3267
x ≈ 0.327
Answer: B
Answer:
4.513451241 sq feet wide x 12.41255213 sq feet
Step-by-step explanation:
Answer:
60%
Step-by-step explanation:
12 kids played. 8 didn't play. That means there is a total of 20 students.
The fraction would be 12/20.
To make it into a percent, divide 100 by the denominator (20) and multiply it by the numerator (12)
100 divided by 20 is 5
12 x 5 = 60
