=cot(8+.216......)
=cot8.216......
=cos/sin8.216......
=6.925...........
Answer:
377 square centimeters
Step-by-step explanation:
Formula: h(2×pi×radius) I know there's a second part but I'm doing this first.
First find the radius, in the problem it says a diameter of 10cm
Divide 10 by 2 to find the radius = 5
I'm going to use 3.14 as Pi
7(2×3.14×5)
7(31.4) = 219.8
Next part, solving for the 2 circles
Formula: 2×pi×radius²
2×3.14×5²
solve 5² first (5×5) = 25
2×3.14×25 is 157
add 219.8 and 157 = 376.8 round to 377
Answer: 377 square centimeters
To solve for n, you are trying to get n by itself on one side of the equation.
n/5 + 0.6 = 2
Subtract 0.6 on both sides
n/5 = 1.4
Multiply 5 on both sides to get n by itself
n = 7
Bobby catches 8 balls / 3 games.
15 games divided by 3 games = 5
Multiply 8 / 3 by 5 = 40 / 15.
Bobby catches 40 balls every 15 games
