The answer is 7 meters.
Area is (pi)r^2
If we remove pi, we have 49=r^2
This means that r=7
Use the pythagoren theorem
Tyce did all the work correctly
Answer:
The correct answer is the final option, 2.
Step-by-step explanation:
[(16+4) - 10] - 8
Our first step in this problem, according to the order of operations, is to simplify what is inside the parentheses. Since there are multiple sets of parentheses, we must simplify the innermost group first. If we add 16 and 4, we get:
[20 - 10] - 8
Next, we must perform the subtraction inside the parentheses. This gives us:
10 - 8
Now, we can perform the final operation.
10 - 8 = 2
Therefore, the correct answer is 2.
Hope this helps!
That's a 240 degree sector of a 9 inch radius circle. The whole circle has area πr² and we want 240/360 of it.
A = (240/360) π (9²) = 54 π
Answer: 54 π square inches
That's the exact answer. An approximation is
169.646 square inches
Answer: 30 days
<u>Step-by-step explanation:</u>
Working together, E & B get 1/45 of the job done per day
Working alone, C gets 1/x of the job done per day
Working together, E, B, & C get 1/18 of the job done per day.
